Firstly he is not autistic, he is the Son of God.
Many of you fail to even accept that Jesus was an actual person (even with the divinity aside), there is written history even outside the Bible to this accord. I just do not see how you can so quickly reject things which have recorded (wriiten) evidence from two thousand years ago, yet so quickly accept the assumptions of modern "science" (things which are outisde of being testable, repeatable, and verifiable). It seems that you are picking and choosing the things from history which will affirm the lifestyle wherein you have decided to live. Christ told you that you would be this way if you were to trust the theories of men, because men look for ways to justify their own desires.
Proverbs 14
There is a way which seemeth right unto a man, but the end thereof are the ways of death.
Matthew 7
Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
Matthew 12
O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh. A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things. But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment. For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
Matthew 14
But he answered and said, Every plant, which my heavenly Father hath not planted, shall be rooted up. Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.... For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies.
John 3
Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness. If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
