But the main ones being:
1. Father was a god
2. They took on a human form
3. They were heralded as saviors (in the sense that they would save the world)
4. Died
5. Were resurrected and now are gods.
And the same with jesus. Yes?
1) The main defense of Jesus being the actual biological son of God is in Matthew and Luke. There are other verses that Christians use to support the idea that Jesus is the son of God, but those are shaky at best.
The birth narratives though were added at a later time. This is very much like the birth stories of Buddha, Augustus, and Alexander the Great. Each one of those historical individuals had miraculous birth stories attributed to them later on.
We can be relatively sure that the birth narratives were added later on for a couple of reasons. The first being that the first Gospel we know of, the Gospel of Mark, did not contain a birth narrative. More so though, the first record we have of Jesus, Paul, never mentions the birth story of Jesus. It is not until Matthew and Luke that we see the birth story, suggesting it was a later addition. More so, looking at the defense that Matthew uses, that it was predicted that Jesus would be born of a virgin, suggests that there was more than just a historical motivation to adding the story.
That is the big difference. The virgin story of Jesus is more similar to that of Augustus, Buddha, and Alexander the Great. It was a later addition. It was used to show an important beginning to an important life. The stories of the figures you are talking about are very different.
By itself, since we know that other historical people claimed to be the sons of a god, or had a miraculous birth, it really leads us no where unless you want to discredit all who had that claim.
2) The Gospels do not state outright that Jesus is God or the incarnate of God. The Gospels, as well as Paul, do label Jesus as a human. Only John really adds a good defense of the idea that Jesus was God in human form.
Mark, Matthew, and Luke may show that Jesus was divine, which Buddha, Alexander the Great, and Augustus were also considered, but there isn't much evidence they believed him to be God. Even in John, the evidence is shaky.
3) Jesus was only labeled as the savior after the fact. However, few of those other individuals were labeled as saviors of human kind.
4) Everyone dies. Not a good argument.
5) Jesus didn't resurrect to become a God. He resurrected in the same sense that everyone was suppose to resurrect later on in order to enter into the Kingdom of God. The resurrection itself fits well within the Jewish idea at that time.
More so, how many of those individuals actually were resurrected?
What you are doing here is taking the lives of multiple god-men and assuming that it was true for all of them. If you do an actual search on the life of those god-men, the stories that predated Jesus, you would see that few of them actually had more than one or two similarities with Jesus. The fact is, they would have those same similarities with various other humans at that time (or at least what was told about them).
