Can't prove the supernatural God

[Esquilax]

Since the claims of Islam come through one man who is the only one who saw or heard anything, then you would have to invent some things that these hypothetical 27 authors witnessed. 

... As opposed to your accounts, written by an unknown number of unknown authors, none of them during the time when the events happened, and none of whom were eyewitnesses? I don't think a christian really wants to be inviting comparisons, here.

The reason people still examine the life of Jesus is that if his claims are true, those events changed everything an an unimaginable scale.

There are an infinite number of patently untrue claims that could, as you say, change everything at the same scale. The reason people still examine the life of Jesus is hundreds of years of cultural inertia backed by socially acceptable indoctrination, a conservative mandate to block out opposing views, and an apparatus of threats and ostracizing to intimidate dissenters.

Your phrase "the only time God has ever been around" shows that you do not understand the result of becoming a Christian--the possibility of having a relationship with God.

You only get the possibility of a relationship with god from converting? How do you tell the difference?
