"Because when you study comparative religion in a serious, academic way, you quickly reach undeniable evidences of "something" that defy the typical atheist's oversimplifications."
Absolutely not. You find that many religions have similar ideas. Many languages have nouns. Many human cultures associate similar feelings with moments of intense fear (that time slowing down effect). Etc. We're all human, we have very similar brains, and so the fact that two very similar beings might reach similar conclusions is certainly not "undeniable evidences of "something" that defy the typical atheist's oversimplifications."
Please don't be a jerk. Atheists are not children.
As for the argument that you can't draw conclusions about something without experiencing it, how do religions come to conclusions about what happens after death? How do car manufacturers come to conclusions about the results of a crash? Not every engineer of a safe vehicle is in a wheelchair. Frankly, imitation is not the only way to draw conclusions, if it was we'd all be hobbling on crutches with an eye-patch and a deaf ear.
