Most evidence for Jesus is indirect, however, they recently found a Jewish limestone burial box (forgotten the actual name for them) with the name of one of Jesus' brothers, and the words 'Son of Joseph', which the archeaologists were saying was likely to be refering to the same Joseph who fathered Jesus, as, somehow it was statistically improbable, to belong to anyone else... try searching one of the popular-science sites for more info...
As to the existance of Jesus today... The bible talks about Jesus living on in a spiritual sense, not a physical manifestation.
Religion is not about control. That is a by product of man's failings exercised through the guise of religion. Relgion itself is quite benign. It is only man who is malignant.
