Is christianity a joke?

I was christian, I became Muslim. God can do anything, right? So why can't he forgive sin? He cannot come into contact with sin.... Well didn't God create everything? Including sin? Yes. If God cannot have contact with sin, yet, Jesus was God, then jesus bore the sins of mankind. So if Jesus was God then God still had interaction with sin. It is a joke that you make God jump through hoops. He must die to forgive. Who the hell are you telling "must" anything. He is God and he "must" do nothing. He does whatever he wants however he wants. He is God. Islam offers all of the prophets and the same God as the old testament. Minus the partners. Jesus was the messiah, but he was not the son of God. God has no children. You feel fear because your soul is searching. It is searching because it is not guided. If God did not create sin then someone else is able to create. If someone else is able to create then God is not singular in his authority. The bible is called the word of God yet, none of the authors of the new testament books claimed God revealed anything to them. The bible means book in greek, God did not even mention the name of the book he would compile within his own book? How many versions of the bible are there? The world was created 6 thousand years ago? There are human remains that date later than that! Islam accepts that the world has been here for millions of years. Islam can even accept evolution, void of human evolution. God is all powerful and if he is he can forgive sins without dying. Or rather killing an innocent sinless being. God needs to die, something has to die, someone who does not deserve it so that God can forgive us. The mayans thought the same way. God is bigger and better than that. The Quran has not changed in over 1400 years. There are over 30,000 versions of the bible in the english language. Not translations, versions. God cannot even protect his own words? The majority of early christians believed that jesus was a prophet and that there was only one God. Constantine, a triune worshiper who worshiped the trinity, the moon, sun, and earth decided at the Nicaea council that jesus was to be worshiped as part of a trinity. All of the christian holidays are pagan in origin, christmas was a pagan holiday celebrating Cesar's birthday. Easter also was to celebrate celestial formations. Where is the validity in christianity?
