OneGod: Wrong answer.
Jesus was Crucified because the Pharisee's and Jews did not like Jesus's Blasphemy ... Blasphemy of what? Blasphemy of Claiming to be the Son of God thats what.
===============================================
In John 10:36, Jesus said, "Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God?"
Obviously, Jesus was being accused of blasphemy for claiming to be God's Son. Where did He say it? In the previous chapter, John 9:35-38, where Jesus had just healed the man born blind, and the Pharisees cast the healed man out of the synagogue.
"Jesus heard that they had cast him out; and when he had found him, he said unto him, Dost thou believe on the Son of God? He answered and said, Who is he, Lord, that I might believe on him? And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee. And he said, Lord, I believe. And he worshiped him."
Ask your Muslim friend, "Only God can receive worship, right?" When he says yes, reply "Then Jesus clearly claimed to be God. Only as God could Jesus, who cannot lie, receive worship."

===============================================
There is NO evidence what-so-ever that somebody other than Jesus was crucified, this is a complete fabricated lie, history does not support this neither does Archeology.
Its plain and Simple ... Jesus was crucified for claiming to be the Son of God, for blasphemy, the Pharisee's/Jews did not like this.
