I've read about the historical evidence regarding Jesus Christ.  From what I understand, the most credible evidence is from Flavius Josephus, and there are even questions regarding his accounts.  Also, correct me if I'm wrong, but there aren't any first hand accounts from known historical figures regarding him. Everything was written centuries later.  I'm not saying he definitely didn't exist, I just question it from what I've read.  

Regarding Muhammad, I've read that even a lot of Islam questions his existence, and historians think that he may be more of a mashup of earlier characters than a legitimate guy.

With either, I'm cool with reading things from better sources if anyone wants to show their evidence.
