Hello, forum. I'm an Atheist, and I'm often confused as to why religion is such a widespread thing. I've come to the following conclusion: I'm missing something. There's got to be some major convincing proof for specifically the Christian God's existence that I've not heard yet. If this is the case, what is it, and why do people find it so convincing? Also, before anybody posts, please go through the following test: take your proof, replace all of the uniquely Christian aspects of the proof and replace them with their Muslim counterparts (God -> Allah, Bible -> Quaran, etc.) and see if the proof still works. If it does, the argument is probably no good.

In short: what is the most convincing proof of God's existence?
