That is different than if millions of people believed in fire breathing dragons, and had experiences with salvation through faith in a fire breathing dragon that came to earth in the appearance of a man and died on a cross for our sins. Most evolutionists that I have seen believe there could be aliens, yet we can't see them. Rational?
The amount of people who believe a proposition does not make it any more true. At one time, almost everyone on earth thought that the earth was flat. Were they correct in that believing that assumption? No, but they didn't know any better. And besides we're talking about evolution not religion, because a lot of religious people accept evolution, many of them are on this forum. And as for personal experience, that is the flimsiest and worst type of evidence. Just ask a magician how easily the mind is fooled. There are always better explanations for the "personal experiences" people have. And I don't think people are lying when they say they've had a personal experience, I just think that they are mistaken.
