Is up down and left right, would you deny the moon exists if it's existance threatened your religion. There are many stories of biblical prophets sinning and being punished. Moses was stopped from entering the promised land, David killed someone and God took his son, Solomon became a idolater, Muhammad ordered the death of hundreds, brutally cut hands and feet off of helpless people who had surrendered. Your claim is about as opposite to history as any claim can be. You say they never sinned, Islam legally refers to them as sinless but believes they did sin, Christianity says only Jesus was sinless. The first two are lies and as usually only the bible which contains more of these prophets that the other two religions put together tells like it is. If a religion forces you to believe the sun is dark, ice is hot, and the earth is square, the wise man rejects that religion he does not adopt it and them argue for those bogus claims. I guess if you views do not conform to reality then the only thing left is to adapt reality.
In a discussion about who is the greates man, the man who could not conquor death takes a back seat to one who could and did.
