How do you know?
Why....the bible is his science textbook. flat earth, geocentric, Luddites need to believe the earth is only 6000 or so years old. Of course advances in medicine that discover and kill the microbes, that are giving them relief from their colds, rashes, etc. are exempt from their scrutiny.
“They’ll figure out that they’re about 4400 years old, once the dating methods are actually accurate.
How do you know?”
A huge body of evidence points to a major cataclysm about 4.5k years ago. The mammoths are part of a huge wider issue of strange animals that belong in a completely different world - wooly rhinos, giant animals of various kinds, huge insects that couldn’t get enough oxygen through their skin to live today, indicating either a much higher oxygen level or a much higher pressure. And of course reptiles, which never stop growing, which is why there is a particular issue of old, giant reptiles, and relatively recent societal memory of these “dragons”.
The dating methods are wildly inaccurate. For one thing the giant insects demonstrate clearly that the atmosphere has changed in a substantive way, so any presumption of steady levels of anything is out the window. The dating methods for longer periods, K-Ar etc have equally ridiculous assumptions.
Whether or not you believe the Bible as a matter of faith, society should accept that people a few thousand years ago were extremely smart, and preserved a record for us. Instead society has the assumption that people a few thousand years ago were primitive and dumb, but the unfortunate truth is that society now is more primitive in its behaviour than society was a few thousand years ago.
Every piece of factual, checkable science backs up the biblical account of a massive cataclysmic flood in which water came up from under the crust of the Earth, from the vast supplies which modern science finally got around to finding out about in the last 10 years or so (google arctic ocean of water under mantle)
There are well funded organizations started by people like Rockefeller which actively promote an atheistic worldview, regardless of the actual evidence.
I sympathize with Christians who feel that Christianity must accept the “established science”, because I used to feel like that. But the truth was I had done ZERO research into the facts, and was basing my view simply on what I had been told to accept without question. The fascinating truth that deserves personal research, is that the Biblical account has at least as much evidence in its favor as the things we were taught in school, and in many cases more so.
