In his book, “The Science Of God: The Convergence Of Scientific and Biblical Wisdom”, physicist Gerald L Schroeder puts forth an interesting timeline which, given the theory of relativity, takes in time from the Bible’s perspective looking forward from Day One (24 hours), and from the Earth’s perspective looking backward in billions of years from the present. Oddly, he comes up with both scenarios being equally plausible.
I however, do have a problem with the idea of 24 hour days being the norm even before the Earth was created, and which is not in synch with what we observe across the universe, in which time is a relative construct, passing more slowly in extreme gravitational environments and more quickly in less massive ones; E=mc² which can, in fact, be demonstrated...i.e., from earth orbit, or in the precession of perihelia of the planet Mercury.
I believe we do more of a credit to God in dealing with His creation in the way it appears rather than in ways we’d misinterpret it to be.
Check out the book linked in post 28. I’ve read the book, and you should, too. Why? Because you have not considered that geology’s belief that there was never a flood could be incorrect. It is undeniably so.
