Not true, the world being flat was much akin to our fairy tales we tell children like the man in the moon or what have you. The world being flat was not a common belief.
Actually, he is right if you substitute the word ignoramuses for scientists. He may be thinking of the same type of “scientists” who today believe carbon dioxide is a threat to the climate.
On evolution, I find it hilarious that when a scientist updates their conclusion based on data, the fundamentalists try to use it to convince people that science is to be ignored. They’re basically saying, “Well, if that jawbone is 2.5 million years old when scientists thought there wouldn’t be any over 2 million years old, then that’s one more supporting point for my absolute knowledge that the Earth is 5,000 years old.”
They apply Occam’s Razor (as adapted by Douglas Adams) - “if the simplest explanation for a phenomena tends to be the correct one, then let’s apply the simplest explanation - It’s a Miracle!”
Thanks!
