I have no problem with a global flood 10,000 years ago and everything today is a renewal/re-birth of God's creation.
There's sufficient evidence for a recent global flood to compete with hundreds of thousands or millions of years.
WHENEVER dinosaurs lived, they were PHENOMINAL creatures !
2 Peter 3:8 “But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.” King James Version (KJV).
Or a million, or a billion if He so chooses. The longer time is based on physical evidence; bone does not become stone in 10,000 years. 10,000 years ago the ice age was ending and the glaciers were retreating. That certainly caused flooding.
Please keep in mind that the Bible was never intended to be a science textbook. Nowhere does the Bible state how old is the earth. We can make calculation and make inferences but that is not what the Bible says. We do not know God’s mind and what information he has given us or the format in which it is given. I do not know how old the earth is. I do not know if there is life on other planets. The Bible is silent on both points.
No known muscle gravity combination makes these things logical or explainable. You have to RADICALLY modify one or both.
