Normally, if we talk about evolution, it's something that is difficult for them to comprehend. It took me quite sometimes even after I had turned agnostic until I admit evolution is true.
Evolutionary theory aside, the order of first appearances found in the fossil record contradicts Biblical creationism, which teaches that all life forms, including humans, appeared at once, with no ancestral species preceding them. Were we to find mammals appearing before invertebrates, or reptiles appearing before amphibians, then that might be evidence of supernatural creation.
I've had some fundamentalists tell me that the fossil record was manipulated by Satan to make it look as if life evolved.
Of course, if one accepts that life evolved, then it follows that we exist unplanned...
I didn't learn much about evolution at school, so I didn't know about that. I didn't really care about fossils either. I thought it was only a hypothesis to explain the origin of human. I didn't know it's an integral part of our life. Fortunately, they didn't teach creationism in biology class, though.

Lol. That was extreme! XD
But I think, the recent religious violence contribute a lot to the rise of the "nones". Pascal Wager is one of the biggest reason why people believe. But when it costs too much, it is no longer worth it.
