I believe that Jesus was a created god modeled after Serapis. Ptolemy made up this new god by combining Greek and Egyptian gods. He also saw himself and the Egyptian Pharaoh and savior of the people in his empire. The Jewish early ideas of a messiah was a scapegoat (sheep) that was sacrificed every year a clean one and the one that depicted their sins was sent off in to the wilderness to be attacked by demons. Early writtings of Jesus showed pictures of him as a sacrificial lamb not even human.
Later as the Christian religion evolved the worship of Marry was replaced with the worship of this god man named Jesus and then the gospels were written. Early Christian and Gnostics writting don’t have Christ on earth even the writings of Paul the ones not considered forgery’s were all about Heaven , nothing about Christ being on earth were mentioned. Many of these ideas were stolen from the Osiris cult.
Again the Jews never saw Jesus as a messiah their idea of a messiah was a god king that would save them like Cyrus did in 539 BCE. Writtings from the Dead Sea scrolls confirmed this and the reason Jesus was placed in the first century is as confirmed again in the Dead Sea scrolls, jews playing around with the book of Daniel messed with the numbers and came up with the idea that a messiah was coming in the 1 century. That’s why we see so many Jewish messiah mentioned during that time.
