You're side may be correct. Our side my be right. BUT If our side is correct, I sure wouldn't want to be in your place at the last roundup!
The important thing to remember is both sides base their opinion on faith. Christians base their opinion on the life altering change Christ made in their life. Something they know as fact, yet cannot prove to anyone. Evolutionists base their faith on a theory developed by scientists. The people who once thought the world was flat.
I don't think your example has it's intended effect. For your example to prove your point, scientists would still have to believe that the world is flat and refuse to believe any new evidence that the world is indeed round.
Science history is full of instances where scientists once thought one thing, only to have it proven wrong. But at that point, they (eventually, in some cases) accept the new facts and move on.
Good point...and it was the church who told them the earth was round!
