Jesus-A mythological figure?

Hundreds of years before Jesus was meant to have been born the pagans worshipped differerent gods(depending on where they came from) who like Jesus:
Claimed to be the son of god,Was born of a virgin on the 25th of december before three shepards,turned water into wine,died on a cross and resurrected at easter and offered his body and blood as holy communion.
There is also no historical records for Jesus actually being a historical figure except for the bible which could be classed off as fiction anyway,Some of the bible scripts were changed and forged, and the gospels were actually written to encourage certain spiritual messages through the fictional character of Jesus.
The pagans did not actually believe that these dying and resurrecting Gods of theirs were real,they taught that they were mythological figures made up to teach special teachings to those who were worthy.In the last century BC, many jews moved to Alexandria, in Greece which was full of pagans worshipping their own dying and resurrecting God called Dionysus.Many of these Jews decided to also follow this pagan god as well as their own jewish beliefs.
In 66CE, Jerusalem was destroyed by the romans and many of the jews were in panic.Many jews proclaimed themselves to be the messiah, but when trying to do miracles, miserably failed.Many jews all over the world now followed both the pagan mysteries and Judiasm and soon many of them had got sick of these fake messiahs.They decided to create theyre own totally new version of the pagan mysteries with a character called Jesus(Joshua in hebrew) to stop all of these ideas and to have theyre own version of the mysterys.
I said before that the pagans did not believe that their Gods were actually historical but believed they were mythological and were created to pass on the hidden truths of the true God.The jews copied this and created theyre own scriptures combining the pagan beliefs with their own jewish beliefs.The jews therefore created Jesus who was both the messiah and the dying and ressurecting pagan god.To create Jesus and his story, the jews used both the prophets words in the old testament and many pagan beliefs.This became known as christianity and this original group of christians were known as the gnostics.
The pagans created their dying and resurrecting gods as myths and never proclaimed them to be historical.The god myths were the "outer" mysteries. The "inner" mysteries were secret teachings that could only be taught from word of mouth to the initiates of the inner mysteries.Initiates of the inner mysteries accepted that their dying and resurrecting god storys were myths created with the intent of drawing people into the pagan mysteries.When an outer mystery initiate discovered the allegories behind the myths, they became part of the inner mysteries.The inner mysteries brought a sense of enlightenment and a relationship with god and sophia(Greek for wisdom).The mythical texts of these gods had secret hidden teachings in them,the main one being the god dying and resurrecting.This was basically an allegory that we as humans could metaphorically "die"from our old sinful selves and be "born again" and know that God was actually a part of us and always had been.
The christian mysteries ran exactly this way, but with the intent of discovering what they called gnosis(Greek for knowledge)as well as the other things already mentioned above.This was the first and proper version of christianity.The gnostics did not believe that Jesus literally died as a martyr,but that his death symbolically represented a profound mystical truth.To imitate Jesus was not to court martyrdom, but to die to one's own lower self and resurrect as the christ within.
Why have I never heard of the gnostics before then, I bet youre wondering.The literalist christians wiped them out, along with all their teachings.They also wiped out the pagans and their teachings too.Why though?About 70 ce when the romans laid waste to Jerusalem, the Jews were spread about the world as slaves and refugees.Many of these Jews were still only part of the outer mysteries and so did not know about the inner mysteries.They were spread apart so far from places of initation that they created their own sect of christianity and called themselves literalists.They took the Jesus myth as truth and wiped out the pagans and gnostics for being "heretical"
