Log rafts, geology and migration
One of New South Wales’ main inland rivers is being choked with woody logs and other floating debris after unprecedented flooding. Several large rafts made of wood and other debris are blocking parts of the Macquarie River in the state’s west. Logjams like these are a natural phenomena on rivers, often after flooding. Willow logs are creating many of the blockages as willows float and then bind together to form rafts bridging from one bank of the river to the other. The longest raft is about 130-metres long, with thick vegetation growing on it since it has been there for months. (more…)

Biblical geology is much more sophisticated than skeptics both inside and outside of Christianity assert. Over 60 years of research, often published in technical journals as well as popular books and magazines, have produced an impressive body of evidence. Sloppy examination of creation science, and their biases, often cause secular scientists, old-earth creationists, and theistic evolutionists to grossly misrepresent the nature of the debate and the quality of evidence supporting the historic Christian view.

How has sea level changed over history?
Scientists think that in ancient times the global climate and sea level went through many cyclic changes. Why do they believe this and what is the pattern of the sea level according to written history? This post addresses the gross features of the global mean sea level (GMSL), and not minor variations and trends. (more…)
Questions and answers about Genesis
The Bible gives a selective history of the earth from its creation to its demise. Many question this. Did you know that there are answers to your questions? Here’s the answers to some questions that were asked recently.
This post is based on questions and answers after a presentation by Dr Mark Harwood of Creation Ministries International (CMI). (more…)
The telephone game
More orally transmitted Aboriginal stories
A message can become unreliable if it passes through many intermediate speakers between the original speaker and the final listener. This is demonstrated in the telephone (Chinese whispers) game in which one person whispers a message to the ear of the next person through a line of people until the last player announces the message to the entire group. What usually happens is that the statement announced by the last player differs significantly from that of the first player. Obviously, if a message (or story) has been retold by many people, some of it can change if people forget parts of what they are told. (more…)
London Bridge has fallen down
In January 1990 a span of London Bridge collapsed, so its name was changed to London Arch. The arch is a tourist attraction along the Great Ocean Road near Port Campbell in Victoria, Australia. Before the collapse, visitors were able to walk from the mainland across the double-span natural bridge. Oceanic erosion of the limestone coastal cliffs caused the formation of the bridge and also caused its collapse to form an arch. Eventually arches collapse to form stacks like The Twelve Apostles, which are icons of the Australian landscape in the vicinity of London Arch (Appendix A).
In this post we will see that rock coastlines are eroding faster than we think. (more…)
Heads I win, tails you lose
Coin flipping is a way of choosing between two alternatives. The person who calls correctly wins. It’s often used to make decisions at the beginning of games and sports. But if someone says “heads I win, and tails you lose”, then you always lose! That’s not fair. But it’s how people often treat the Bible. They are willing to accept many ideas, as long as they aren’t based on the Bible.
For example, Australian researchers have investigated Aboriginal stories describing times when sea levels were lower than today (Reid et al, 2014). The orally-transmitted Aboriginal stories were written down after Europeans arrived in Australia in 1788. The stories describe coastal flooding which the researchers identify with the rise in sea level since the last ice age to its present level about 7,000 years ago on the geologic time scale (Appendix A). See Appendix B for the equivalent biblical dates. The team analyzed the contours of the land where the stories were told and used reconstructions of prehistoric sea levels to date the origins of each of the stories. They claim that these stories can be 10,000 years old which represents accurate oral transmission across 400 generations. Nunn and Reid (2015) expanded their analysis to 21 stories about coastal drowning that in most cases was considered likely to recall the effects of postglacial sea-level rise more than 7,000 years ago. They also noted that “no Aboriginal stories are known that talk of the sea level falling and exposing coastal lands”. (more…)
Life in the Ice Age
Scientists believe that the Earth goes through cycles of climatic change. Periods of lower temperatures are assumed to result in long-term periods of glaciation, which are known as an ‘Ice Age’. As the causes proposed for these Ice Ages seem to be deficient, there is reason to believe that there was only one Ice Age.
This post is based on a children’s book by Hughes and Cosner (2018).
Was there really an Ice Age?
Evolutionists say that there have been many Ice Ages throughout history (Appendix A). Actually there was only one Ice Age, and it was caused by Noah’s Flood. Though the Flood lasted only one year, its effects on the climate lasted for centuries! Hot underground water was a major source of Flood waters, so even after they retreated back into the oceans, the water stayed warm. Also, massive volcanic eruptions would have poured ash into the air, which blocked out much sunlight over the land. So the land would have been much cooler. Then some of the warm water evaporated into clouds which then dropped much snow over the cold land. Over centuries, this packed into huge ice sheets covering a third of earth’s land. We can even see the effects the snow and ice had on the earth today; the ice at the North and South Poles is left over from this (about 10% of the earth is covered in ice); the alpine glaciers; and the glacial landforms and sediments. Because these effects are seen on the current land surface, it is clear that the Ice Age occurred after the Flood. (more…)
