Ancient Persian myth in the origins of Christianity ?!?

There were sixteen crucified messiahs before Jesus. There are many similarities between Jesus and Horus, Mithras, Osiris, Dionysus etc. God keeps repeating himself. Myths may have influenced each other, that doesn't mean they're not true. They are archetypal stories which often have more than one expression. Jesus studied the Vedas etc. so he would have recognised foreign deities and maybe incorporated them into his system.
