Just my perspective, debates welcome.
A believer has not many questions to think answers for, they have one black hole - God - that they can throw the question at it gets sucked into the mysterious nowhere, and they breath in relief.

A non-believer on the other hand, has a lot to think about. Just for starters, a way to prove to the believers that there might not be a God at all. This is a bit strange because the way I know it, unless shown something does not exist, and its be believer's responsibility to do so - like the bigfoot - most of the world does not believe in it, but the believers try and keep the news alive with a sighting, with a foot mark, with a long range blurry picture.
