this is a weird question...in a way, it is a "not thoroughly thought through" question.
any religion can't be proven or disproven...be cause it is based on blind faith. in other word, it has nothing to do with what's real or fake....
everyone knows that "jesus" was a real person, due to historical references. however, no one can prove that jesus was god's son or that he is the ultimate god. these godlly conclusions are based on beliefs. anyone religion is guilty when we are talking about "proof" or "facts"...it can't be done (not now anyway).
