A strange statement, seeing as the people who wrote the bible weren't there either. In the life of Man the bible writers were in the last 3500, of a time that stretches back 500,000 years. So not even in 1% of the time.
How do we know this? We can see the proof.
And in all those layers, all around the world, you and I can see for ourselves Genesis is a fictional story.
You and I can see how life evolved on Planet Earth. Evidence we can find, touch, own and learn from. Something the bible and priests always want to deny.
And to claim because the bible contains the word serpents, that explains dinosaurs is frankly absurd. As absurd as some say they were put there to confuse us, there is no confusion. So OP if you want to know the truth about Genesis, don's read a Bronze Age book. Google the nearest place you can visit to see the
different strata in sedimentary rocks. You may even find fossils for you to own.
And please do watch the TV program "
Your Inner Fish". It will scare the Fundamentalists, because it's true to what we have learned so far. Like how embryo
prove how we go back to reptiles. And
even fish. The bible doesn't have an answer for the truth.
