Christian Theism has not been falsified yet

Krishna's mother was not a virgin. But he was transferred into a virgin's belly to be born, according to literature from ISKCON. I guess you are right that that isn't strictly a virgin birth. Buddha had those claims made for him. His mother, Maya, was supposed to have been a virgin. Mithras did indeed have a bull sacrifice. But he died and rose somewhere along the way. The Babylonian Tammuz, after whom one of the Jewish months was named, did indeed die and rise, at least according to some sources. Adonis you may be right about. I don't know of an Arabic Tammuz. The Babylonians were not Arabs, nor speakers of Arabic.

Tammuz is regarded as a life-death-rebirth god. He died at the onset of the poor weather each year and was reborn when better weather came. The god of vegetation, he guaranteed the rebirth of food. Wikipedia info.

And wikipedia wrote that better than I did. I'm in a hurry.

So Tammuz was linked to the crops.  Makes perfect sense that he would die and be reborn, multiple times at that.  Thus, no real correlation to the Jesus resurrection as you had previously tried to imply.

Any god that dies and is reborn can be likened to Jesus. I mean, think. Easter adopted symbols like bunny rabbits, eggs, and even its name from the Germanic goddess of the spring, new life, and rebirth. The whole concept of Jesus dying and rising from the dead tapped into the ancient Israelite need for several things. 1, the fact that Israelites wanted a god of death and rebirth. Two, they wanted a messiah. Three, they were interested in the Eastern mystery cults. Christianity had everything that would appeal to Hellenised Jews and Goyim. But especially the Goyim, after Paul got hold of it!

Many of the Christian holidays are just an adaptation of pagan rituals.  This was done to try to make the transition into Christianity easier for the once non-believers so they wouldn't stop the celebrations they had been holding for generations but would rather celebrate God instead of the goddess of spring or whatever other deity.  The best proof of this is Christmas itself. Jesus most likely was not born on December 25, however there was a pagan festival which was observed near this time of year in ancient Egypt (source: http://www.goodnewsaboutgod.com/studies/holidays2.htm).

The thing about Jesus is the fact that he was a mortal being whom was killed and rose from the dead, and he only did this once.  He died for the salvation of his followers' souls.  Resurrection is a common theme in faiths but it is usually a god which dies and is resurrected, not a mortal.

Jesus is considered both God and man. Remember the Hypostatic Union? They were not (and still are not) simply commemorating the death and return to life of a mortal. They were (and are) partaking of God himself in that bazarre communion ritual. And the Romans had a festival, that of Sol Invictus, at the Winter Solstice. Many of those activities were brought to Christmas too.
