I just wanted to know the evidence or if there is any for these key things:
Jesus' resurection
Jesus' virgin birth
Jesus' existed 2000 years ago.
And if these are all true how does this prove that he is the son of god? Couldnt it just prove he was the messiah a phrophet, not divine.
As to whether Jesus existed, I would say that can be established beyond all reasonable doubt. To take just one example, which belongs to a class of arguments known as the Principle of Dissimilarity:
1.) In the New Testament it is recorded that Jesus was baptised by John the Baptist.
2.) That is something the Church is extremely unlikely to have made up.
3.) Why? Because the early Church wanted to present Jesus as the "main man," so to speak, and his baptism by John suggests that he might have been a disciple of John. The gospel writers show every sign of wanting to play down the significance of the Baptism, and John omits it altogether.
4.) So, if it wasn't made up, it must have been a historical event, which clearly implies that Jesus existed.
As to the Resurrection, it seems to me that, if it didn't happen, we are left with a historical puzzle. Namely, out of the half dozen or so putative messiahs in first century Palestine, why is only one of them remembered 2,000 years later, with approximately 2 billion followers, whilst all the others have been long since forgotten by almost everybody?
I am agnostic about the virgin birth. It may be historical, or it may be there to serve a theological purpose (to emphasise Jesus' unique origin in God.)
