Sith - What people are attempting to do is educate you about reality. You may find that statement insulting but the fact is that you do not understand basic logic and common sense. The proof of this is when you state as a fact that, “... jesus spread islam, moses spread islam, adam spread islam...”.
That statement by you is complete and utter drivel and I have heard it many times before from other Muslims desperately trying to portray their religion as the one true faith. Unfortunately for them and you, the assertion is demonstrably false. This is not a question of faith but a question of logic and rationality. If you're going to make the religious claim that the first man on Earth – Adam – was in fact a Muslim who existed several millennia before Mohammed was born, then you're going to have to have some pretty remarkable historical and scriptural evidence to back up that claim. And there simply isn't any. The only 'evidence' is that created by Mohammed himself or by the various authors of the Hadiths (one of which claims that Adam was 60 cubits tall [90 feet or 27 metres] and lived for 930 years). This is not evidence by any stretch of imagination – it is irrational, illogical assertion and nothing more. The same goes for suggesting that Jesus and Moses were also Muslims.
As Naomi rightly points out, Jesus wasn't even a Christian. Both himself and Moses were Jews. As for Adam – and let's forget Eve (or Hauwwa; strange how you left her out in your statement) - neither of them were Muslims, Christians, Jews, Mormons or even Scientologists. They had no formal religion of which to speak – they simply believed in the existence of 'a' God.
I realise that a certain amount of suspension of disbelief is a prerequisite for being religious but that does not have to mean that you disengage your brain entirely.
