What makes your faith true?

[Fake Messiah]

The Emperors of Japan have all died, Muhammad's revelations haven't come true and he is also dead, Krishna had a father and mother therefore created, therefore Krishna has no providence. Those who worship these deities may have faith in them, but those deities are shaky at best.
My God was not created, has always been and will always be, His promises have always been true and as creator has providence over all things, so I can't be like them because my God is unlike theirs in every way that's positive.

Well that is an answer from the faith, like "Well, the Dalai Lama reincarnates. Duh!"

Certainly you don't think they don't see your god as any better then you see theirs?

Those people which gods you downplay don't see them "just as fake humans", but see Krishna as as a son of god that came to destroy sins.
They could also and do downplay your god the same way. They could say his prophecies failed like "there are some of those who are standing here who will not taste death until [they see Jesus returning in his kingdom]" - which did not happen; or when he said that stars will fall from heaven - meaning that he didn't know what stars are and he certainly didn’t understand the size of a star or its distance in relation to the earth.
Jews dedicated many webpages explaining how Jesus was not the messiah, like JewFAQ.org’s article "Mashiach: The Messiah."

And they could say he was not son of god by using christian's own scriptures, just like you're supposedly using theirs. Because of that there were (and still are) even Christian denominations that don't see Jesus as god but as an inspired man like: Ebionites, Unitarians, Arians.

Also people that have personal relationship with emperor of Japan could downplay your faith just as you did theirs. You say that because emperor of Japan dies people can't have supernatural personal relationship with him and yet even to people like yourself death and even human origins (although emperor is seen as divine) was never a barrier to think that they have a supernatural relationship with somebody, like with saints.

So what makes you think your criticisms against their gods are any better then their criticisms of your god (like for example JewFAQ.org’s article “Mashiach: The Messiah,”)?
