Rehwinkel has a very good book on "The Flood," old but full of great insights. He had a theory about a coincidence. Every culture has a death day where people dress up as dead people, ghosts and skeletons. Well, death is universal. But this death day is almost the same all over the world. We call it Halloween. He wondered if that was the date of the Flood starting, remembered in cultic fashion.
The Bible teaches that a global flood killed all life on the land. I believe the Word and I also enjoy seeing all the evidence left behind for the doubters.
Also interesting to think about the mythological gods, how most all seem to have existed in both Roman and Greek mythology Have you ever wondered if maybe such people existed? think about what the possibilities are before the flood.. the nephilim are spoken of in the bible as large powerful people created from demons that forsook their natural place.. the spiritual realm. These mythological stories could just be far fetched truths... you know how things get twisted after a while.. and the stories about these gods are entertaining
