Why does creationism need this wild global flood theory?
There was a tsunami 8,000 years ago in the Mediterranean. It was caused by a volcanic avalanche in Sicily. How do we know that this was not the “flood” pouring down on the land?
Why does creationism need to exist? I think creationism at its heart is just one more iteration of the maxim: "Who do you believe: me or your own lying eyes?"
If yoi interpret the Bible one way, but a veritable mountain of real-world observation says the opposite, then maybe the problem ain't with science.
