Ok, I was with you until you started saying Jesus was an evil alien reptile.
Yes, the asteroid belt between Mars and Jupiter used to be a planet, but was destroyed in the intergalactic war. Mars was ravaged by this war as well, but it maintains an underground population.
Aliens, of various species, still inhabit this solar system in space colonies. In fact, the big red spot on Jupiter, which appeared virtually overnight, is one of the Arks used in this war.
Jesus however was NOT evil or reptilian, but more so an enlightened being. Though not necessarily the Son of God, he was an initiate of the Mystery Schoold and passed through Wisdom Orders during his missing years through the Bible. His missions, through the New Testament, was preaching against the fallacies of the Jewish and Hindu (Apocrypha) religions. He was a revolutionary, that was more a threat to the Roman Empire then anyone else. Jesus was not evil, he was sacrificed for the greater good, which started a new religion... one that was hijacked at its infancy.
Rome capitalized off of all the self-sacrifice and martyrdom that went into this religion. The early followers were rebellious and believed in something greater than themselves. Rome couldn't squash this new system of belief, so they claimed to convert, when in actuality they took control of the religion.
Most of the population weren't present at the multiple councils that put this religion together, it was only high priests and high officials of Rome that made all the decisions, especially when compiling the stories that made up the New Testament. Those who opposed the way Rome put all this together were struck down.
The populace overjoyed, taking it as a great victory when the Roman Emperors converted to Christianity, but it was actually their defeat.
The Emperor and puppet popes took the reigns. Though Jesus's word survived in only 4 books, the interpretation of what he meant by those words were decided upon by the new leaders of the Church, which led to the Dark Ages and inquisition. The people were slaves yet again. This wasn't Jesus' fault, but those capitalized off of his words and used them to maintain control.
