I wish you the best when you go to the creationist museum. Please don’t spend too much time defending evolution. Most in the audience will have already made up their opinion long before they enter that room. Some people in that room will think you’re going to burn in hell. I assume you may not think highly of their beliefs either. You need to explain how creationism is incorrect, and provide convincing scientific evidence to have creationists question a core belief. The best way to have them question this is to show evidence of civilization that is over 10,000 years ago. The compelling issue of this evidence is its location. They’re all deep under the ocean and scattered around the globe.
Oh, yes. There was a great flood, a Glacial flood and ocean never receded. It lasted over 8000 years. Oceans rose four feet a century on average, sometimes even 9 feet in one year. Civilization relies on a stable coastline, and recorded history starts only two thousand years after the ocean levels stabilized.
The prior time when there was stable coastline was between 25,000 and 16,000 years ago, when ocean levels were 350 feet below current levels. There is evidence of civilization at that depth, exactly where it would be expected.
There is also a question of morality.
Those who believe in evolution have a disagreement with creationists. “Evolutionists” believe that life is a flow, like a never-ending blossoming flower. Creationists believe in a beginning date, and do not believe man lived before that date. What is the morality in denying the existence of earlier generations?
