Possible theory on early contact between xenomorphs and humans, were they jewish

basically in the movie we have determined that we are the product of one of the engineers who sacificed himself to give us life. and through out the years they have been in contact with us which we know via the cave paintings. the engineerswho obviously engineered a biological weapon for killing the humans on earth had finished the weapon at around 100AD, roughly around 100 years after the birth of christ. we can assume that we did something to piss the engineers off because the cave paintings showed them as friendly however what turned them to hate us? i believe it was the birth of christ who was actually a xenomorph (one of the black aliens as seen in the other alien movies) this became obvious to me as he was the child of a virgin. so the only way that is possible is that she was impregnted by a facehugger. and since jesus christ started spreading the word of the "lord" who was thearetically an alien opposing the original humans the original humans did not take this kindly. they were offended that someone raised by their creations turned everyone against them in the form of christianity.
