Make sure it's a legit question, not something like 'how many people have you bombed?'
If you ever did have a question, I'll be happy to help and if I can't I'll try and direct you to the right place.
I've analysed Christianity quite a lot. From trinity to the resurrection, Paul etc. I can talk to you about why I don't believe in Christianity.
Ultimately, we accept all of the prophets of the O.T. We believe John the Baptist was a prophet, and Jesus was the messiah, God's Word, a prophet who delivered the gospel (the original message from his mouth) and that he will rule the earth as the king of kings in the Messianic age. We also believe he was born of Virgin Mary (who is esteemed as the most Holy woman to walk the earth, by Muslims).
Our fundamental difference is that we just don't think God is a trinity, and we don't believe he died for our sins.
This is identical to the Islamic declaration of faith, and was certainly the same for the time of Jesus:
'Now this is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent.'
Eternal life for Islam is 'there is only one God, and Muhammad is the messenger/whom God has sent'.[/QUOTE
