Former Atheist Here- Want To Debate Truth of Christianity

Alright. Before I begin to make my argument for why Christianity is true I'd like to define a key term, God. I mean by God an all-powerful, supernatural Creator of all things. Now there are two things one must prove if one wants to convince others of the truth of Christianity. The first is the existence of God (this is the simple part). The second is the divinity of Jesus (this is harder but not impossible to argue). First, the existence of God. There are many reasons, from looking at the world, to believe in the existence of God. For example, the beginning of the universe. All evidence from cosmology suggests the universe had a beginning. This means there was some definite time at which the universe sprang out of absolutely nothing. But this is obviously absurd. If things came from nothing, we would be living in a sort of "Hitchhikers Guide to the Galaxy" type of universe where sperm whales and teacups would appear in the sky at random. This shows the universe could not have come from nothing, unless there was something to produce it, like a whale needs parent whales to produce it. The thing that produces the universe, once we reach this logical and obvious conclusion that the universe springing out of nothing is absurd, must be something which does not consist of energy or matter, or space-time. Now the only things that fit that category are abstract objects like mathematical numbers or sets, or else some kind of mind beyond the universe. But the first kind of thing, abstract objects, don't cause things to occur, therefore we must draw the conclusion that a disemodied mind exists beyond the universe. This mind must be possessed of unimaginable power, since it created the universe out of nothing, and must also be personal because a mind just is personal. Therefore we can conclude a trancendent, powerful, and personal disemodied mind exists. This is what most Christians mean by God. Now we come to reasons for believing Jesus was divine. In order to prove that I will show the ressurection occurred. If God raised him from the dead it confirms that Jesus was divine because this was supreme confirmation of his divine claims according to the New Testament. In order to prove he was resurrected I will analyse the historical facts surrounding Jesus' ressurection to see how likely it was that he was resurrected. I will use Bayesian analysis to show how on historical evidence we should believe Jesus was raised from the dead. Let's let T=theism, let R= ressurection of Jesus, and D= the historical facts about the ressurection of Jesus (eg the empty tomb, the post-mortem appearances of Jesus to others). The probability of T is the argument I made above. Let's say the argument is 0.99% likely to prove God EXISTS, and the prior probability of atheism= 1-P(T) P/T= 0.00001% (unlikely but not impossible) P/1-P(T)= 0.00000000001% (vastly unlikely) We balance the equation by assuming that there is equal probability God does not exist and that he does exist, and timesing these probabilities P/T* P/1-P(T) Then we plug in the historical facts concerning Jesus' ressurection by dividing those probabilities by the P(D|R). Let's say P(D|R)= 0.75. When we divide the numbers, we find the total of them is 0.977, so it is 99.7% likely that God exists when we look at the historical data on Jesus' ressurection in a non-biased way. Thus we confirm Jesus was divine and we prove that God existed as Jesus of Nazareth.
