Evidence of Noah’s flood

Flooded river - Jun 2016 400pxAfter some Australian motorists drowned when their cars were swept away by floodwaters in June 2016, university researchers investigated how much force it takes to wash cars away from the road. A 1 tonne vehicle was moved by water 15 centimeters deep flowing at 3.6 km/hr. It was carried away in 60 centimeters of water. A 2.5 tonne vehicle was moved by 45 centimeters of water and began floating in 95 centimeters of water. The cars were moved so easily partly because even shallow water can be deceptively strong, and partly because modern cars are so air-tight that instead of taking on water they get pushed along by it. Even slow-moving water is powerful because water is heavy: each cubic metre weighs 1 tonne. They concluded that vehicles became vulnerable to moving floodwaters once the depth reached the floor of the vehicle. This is consistent with Queensland advice that “Water deeper than the bottom of your car door is enough to float your vehicle away, or splash the engine and cause it to stall”.

If a shallow river can be so powerful, a global flood would be an enormous catastrophic disaster. If this happened about 4,350 years ago, surely there would be some evidence of it still visible today. This blogpost is a summary of eight main points that were made by Dr Tasman Walker in a presentation on “Evidence of Noah’s flood in Australia”.

What would we expect to find on earth if there was a global flood as described in Genesis chapters 6-8 in the Bible?

Fractures in the earth’s crust

The two main sources of the water for the flood are described as “all the underground waters erupted from the earth, and the rain fell in mighty torrents from the sky” (Gen. 7:11-12NLT). Subterranean water burst from beneath the earth and there was torrential rain for 40 days. The flood waters rose to cover the highest mountains of the pre-flood world by 8 meters (Gen. 7:17-20). By the way, Mt Everest didn’t exist before the flood because there are sedimentary rocks with marine fossils on its summit.

If underground water was erupting from the earth on a global scale you would expect that the earth’s crust would be fractured. Today major fractures are seen in the earth’s crust around the edges of the continental plates. When these continental tectonic plates move against each other there are earthquakes and volcanic activity. Such geological activity around the Pacific Ocean is called the “ring of fire”.

So we would expect to find fractures in the earth’s crust and we do. These fractures are evidence of Noah’s flood.

Billions of dead things

If a catastrophic flood covered the earth for six months you would expect to find billions of dead things all over the earth. “Everything (except those on the ark) that breathed and lived on dry land died” (Gen. 7:22NLT). Because such a flood would transport huge amounts of sediment across the earth, most of the creatures that drowned would be buried in the sediments. Because such a flood would also transport huge amounts of sediment into the ocean and cause a depletion in oxygen levels, many marine creatures would die and be buried as well.

Queensland dinosaurs 400pxAt Winton in Queensland, there are many well-preserved fossils of dinosaurs and marine creatures. Dinosaur fossils have also been found at Muttaburra (Queensland). These fossil-bearing sediments extend across the Great Artesian Basin into New South Wales, South Australia, and the Northern Territory, while marine fossils are found in other parts of Central Australia.

So we would expect to find billions of dead things (fossils) in sedimentary rocks and we do. These fossils are evidence of Noah’s flood.

Evidence of rapid burial

If a catastrophic flood covered the earth for six months you would expect to find evidence of rapid burial.

At Richmond in Queensland an exceptionally well-preserved marine reptile fossil was discovered in 1990. It’s a plesiosaur that’s over 4 meters long. In order to be preserved so well it must have been buried rapidly. Fossils of land animals are also found in this region, such as the ankylosaur (an armored dinosaur).

So we would expect to find evidence of rapid burial and we do. These fossils of creatures that were buried rapidly are evidence of Noah’s flood.

Sediment covering huge areas

Great artesian basin 400pxIf a catastrophic flood covered the earth for six months you would expect to find evidence of sediment covering huge areas.

Geologists find that layers of sedimentary rocks extend across large areas called sedimentary basins. They can contain coal, oil and gas that’s used as fossil fuels. For example, the Great Artesian Basin and the Sydney Basin. There are also examples in other continents. And there are also offshore sedimentary basins on the continental shelf of countries around the world.

So we would expect to find evidence of sediment covering huge areas and we do. These layers of sedimentary rock across huge areas are evidence of Noah’s flood.

Evidence of raging waters

If a catastrophic flood covered the earth for six months you would expect to find evidence of raging waters. As these flood waters would have been highly energetic, they would have transported material along with the flow.

3 sisters 400pxThe Three Sisters rock formation at Katoomba is composed of sandstone, which was laid down by water. This layer extends across the Sydney sedimentary basin. An examination of the sedimentary layers evident in road cuttings shows layers 1-2 meters thick, which indicates that a lot a water was involved in transporting and depositing this sediment. This water must have been continually rising (to enable continual deposition). There are many cross-beds that go at an angle across the strata. They are formed when the sediment layer builds sideways.

Uluru 400pxUluru (Ayers Rock) in the Northern Territory is made of sandstone and the layers have been tipped up so they are almost vertical. These strata are visible as parallel lines on Uluru. This shows that there hasn’t been any significant erosion between the deposition of the strata. So there was rapid deposition – one layer was laid upon the other quite quickly. When we look at a geological cross-section through Uluru it is evident that a lot of sandstone has been eroded from above Uluru. The grains that comprise Uluru are angular, poorly sorted (a large range of particle sizes) and well-preserved (not weathered) which is consistent with rapid deposition.

Olgas 400pxKata Tjuta (the Olgas) is a group of large, domed rock formations 25km west of Uluru. They are comprised of large boulders (30-50cm in size). These all face in a similar direction, which is the direction of the water flow that transported them to this site. They indicate highly energetic flood waters.

So we would expect to find evidence of raging waters (which transport and deposit lots of sediment) and we do. These cross-beds, parallel sedimentary strata and boulders are evidence of Noah’s flood.

Evidence of massive erosion

If a catastrophic flood covered the earth for six months you would expect to find evidence of massive erosion. After the flood waters peaked and subsided, they would have flowed off the continents and eroded material away as they flowed back into the ocean.

When you stand at Echo Point overlooking the Three Sisters, you see that Jamison valley is cut into a flat plateau. How did it get so flat? As the floodwaters moved across the continent, they eroded the surface flat. That’s how plateaus formed all around Australia and around the world. Jamison valley is much larger than any valley caused by Kedumba River that flows through it (the same is true for the Grand Canyon in USA). Geomorphologists call these overfit valleys – the valley is too big for the river. How did it get to be such a large valley? The valley was carved by a lot of water and not by the current river. As the floodwaters subsided, when hills became exposed, the water carved out large valleys transporting the sediment out of the area.

This is also evident at Carnarvon Gorge in Queensland at the intersection of the Great Artesian Basin and the Bowen Basin. A large valley has been cut into a sandstone plateau that’s capped by basalt. As material has been eroded away, these sedimentary layers originally covered a much larger area.

As a result of such erosion, rivers can flow through mountain ranges rather than around them. For example, the Heavitree Gap in the MacDonnell Ranges near Alice Springs. How did that happen? Many explanations have been proposed, but none of them work. As the floodwaters subsided, the higher parts of the ridge become exposed and the water flows between the gap between them. As the waters continue to drop, they continue to erode through this gap until when the water has all subsided the gap remains and a river flows through this gap today. It’s called an air gap if it doesn’t go down to the level of the adjacent surface.

So we would expect to find evidence of massive erosion and we do. These large overfit valleys are evidence of Noah’s flood.

Evidence of youthfulness

If a catastrophic flood covered the earth for six months about 4,350 years ago, you would expect to find evidence of youthfulness.

At Kata Tjuta there are a few boulders lying around, but not many. And there is a small apron around it, but not a large one as if it had been eroding for millions of years. And there’s very little debris around the base of Uluru or Kata Tjuta. This indicates that it was eroded recently.

So we would expect to find evidence of youthfulness and we do. The lack of erosional debris is evidence of Noah’s flood.

Worldwide memories of the flood

All of the people of the earth are descendants of the eight people on Noah’s ark. As the global flood occurred about 4,350 years ago, you would expect to find memories of Noah’s flood in the different people groups around the world.

Cultures around the world have flood legends (or stories). For example, the Bundaba Flood Story of the Aboriginals at Broome is given in the appendix. Common features in the stories are that there was a moral cause, people were drowned, there were people saved in a boat, and there was a bird.

So we would expect to find worldwide memories of the flood and we do. These flood stories are evidence of Noah’s flood.


There’s plenty of evidence in Australia of Noah’s flood. Evidence of eight aspects of Noah’s flood show that what we observe is consistent with what the Bible says. This flood is a key to connecting the Bible to the world around us. It explains the sedimentary rocks and the fossils. And it washes away the millions of years that are assumed by evolutionists.

It also helps us understand the world. It makes sense of biblical creation. Death and suffering came after Adam and Eve and not before them because they were a consequence of sin. Whereas according to the idea of evolution, death and suffering over millions of years brought about our existence.

Questions and answers

What is rapid burial?
When animals and fish die today they disintegrate and are recycled. They aren’t fossilized. So, how were the fossils preserved? If they are buried quickly it stops them being scavenged and it affects how bacteria destroys animal’s bodies. So rapid burial is necessary to produce fossils.

What about continental drift?
Like evolutionists, creationists fit the evidence into their world view. There is a creationist model of how the continents were all together before the flood and they broke apart during the flood (catastrophic plate tectonics). The earth’s mantle (beneath the earth’s crust) can suddenly lose its strength under high temperature and high pressure. So the continental movement could have happened very quickly (continental sprint) during Noah’s flood. In the second half of the flood the ocean basins sank and the continents rose: “Mountains rose and valleys sank to the levels you decreed” (Ps. 104:8NLT).

What does “the earth was divided” in the time of Peleg mean (Gen. 10:25)?
This is just before the tower of Babel when God divided the people into different language groups and they dispersed across the earth (Gen. 11:1-9). This is what we believe it means. It couldn’t be the separation of the continents because if it happened a few hundred years after the flood that would be a huge catastrophe and many people would perish and there is no evidence of this in Scripture.

When was Mt Everest formed?
The earth’s crust moved during the flood. The mountain ranges like Mt Everest were elevated towards the end of the flood. The mountians we see today rose up at this time. The shapes of the mountains were carved by the waters of the flood (and any post-flood ice).

Do we know how high the mountains were before the flood?
No. We know there were mountains before the Flood because the Bible speaks of them (Gen. 7:19-20). But we don’t know how high they were. Some creation geologists speculate that they weren’t as high as those today.

What about the ice age?
It happened after the flood. The flood is the only thing that explains the ice age. It was due to warm waters after the flood caused by the addition of hot subterranean water and by heat from volcanic activity. And large amounts of volcanic dust and aerosols in the atmosphere would have reflected solar radiation back into space causing low atmospheric temperatures. Warm oceans evaporate water, which then moves over the land. Cold air over the continents results in this water precipitating as snow. And the snow accumulates forming ice. Because the ice was not fully melted the following summer, the ice built up from year to year. It has been estimated that the ice accumulated for 500 years after the flood and then retreated to where it is today over another 200 years. But evolutionists don’t have an adequate explanation for the ice age.

What about global warming?
Climatic modelers try to include the ice age, but they don’t include Noah’s flood. They think that the earth’s atmosphere is unstable and a little change will tip it over the edge. Whereas the earth’s climate is very stable – after the huge climatic disturbance of the global flood, it took about 700 years to come back to equilibrium.

What about the decrease in longevity?
Before the flood people typically lived over 900 years. After the flood this decreased exponentially towards 100 years (David) and then 70 years. It was probably a genetic change and not an environmental one because after the flood Noah lived 350 years (Gen. 9:28) and Shem lived 500 years.

What about the Behemoth described in Job 40?
We believe it was a brachiosaur (sauropod) dinosaur. The size of its tail is one of the reasons. We believe that dinosaurs and people lived together. They were called dragons and other names because “dinosaur” is a modern name.

Appendix: The Bundaba Flood Story

Long, long ago there was a great flood. It happened because some children found the “winking” owl and plucked out all its feathers. The bird flew without wings, into the heavens and showed himself to Ngowungu, the Great Father. Ngowungu became very angry and decided to drown the people.

Later the people saw a small cloud rising which grew bigger and bigger till it spread all over the sky. The thunder began to roll and crash and the people were greatly afraid. With the rain and thunder was a terrible wind which broke great limbs off trees and rooted up others. During this terrible storm there was a noise above the awful crashes of thunder. This noise was coming from the north. The salt water, the sea, came pouring over the ranges from the north. The flood rose higher and higher till all the land was covered except the tops of two or three mountains.

A bird with a leaf in its mouth flew in front of them showing them the way to Mt. Broome. From further west a man and his wives with a dog were battling their way in a canoe when a bird with a leaf in its mouth flew in front of them showing them the way to Mt. Broome. They eventually reached Mt. Broome and landed there where some other survivors were.

Then Djabalgari, the great left-handed man incised his little finger and let the blood trickle down into the flood waters. The waters began to go down and eventually disappeared off the country. All other people were drowned.
