I think I started questioning witness beliefs on evolution ever since very young, and studying the creation book, and I remember it saying 'all the evidence 'supporting' human evolution could fit into a human casket, and that is exactly where it belongs"' or something very similar. I was like, really? There is enough evidence to fill a casket? That sounded like a lot of evidence to me! You could fit tons of stuff in a casket.
And then visiting museums. They have not only found dinosaur bones here and there and pieced them together, they have found whole, complete skeletons! And MAN were those canine teeth huge! Those teeth were NOT for chewing plants!! And those claws, what were they for? And the armour?? so yeah, I knew they fit somewhere into the scheme of time, and it was definitely a long, violent scene. Back then it was more of an either/or thing to me. I didn't believe that both could be true. But since letting go of fundamentalism I'm cool with science.
