And there is also multiple documents from Christian and non-Christian (even opposing) sources that testify tot he Resurrection story.
Sorry, but this isn't even worthy of serious debate. The Bible is a religious text, not a historical document. The overwhelming majority of it has no corroborating evidence whatsoever, and that's without taking into account the fact that some of it is supernatural.
Sorry, I got to laugh at this suggestion.
Laugh all you like. You think the Bible is a historical text and that the resurrection is a historical fact. Seven day creationists also laugh at people who understand evolution. They may think this portrays confidence, but it actually just makes them look extremely silly.
So the Roman empire successfully engineered a massive conspiracy with thousands and thousands of New Testament copies scattered all over the known world and not one document survives to dispute your conspiracy theory?
You've just demonstrated that your understanding of the true history of Christianity is just about non-existent. What we call "The New Testament" didn't come into existence until the first councill of Nicea in 325 AD. The Flavians ruled the Roman Empire between 69 and 96 AD.
In short, you haven't got the faintest idea what you are talking about, in terms of actual history. To be fair though, neither have 90% of the other Christians I've ever discussed this with. Unfortunately they tend to approach this topic with a pre-concieved, and very firmly held idea that the New Testament is a historical document. In reality it is nothing of the sort, and has a complex and fascinating history of its own, as do the stories it contains.
If you were remotely interested in finding out the truth, I'd be happy to talk to you at length, but if you're like most Christians then all you are actually interested in is finding ways to continue believing the nonsense version you currently believe.
God is Truth. You should not be scared of it.
