The Virgin Mary’s immaculate conception
Was Mary made pregnant by an alien, perhaps by artificial insemination? In which case, Jesus would have been a son of a an alien "watcher", like Noah or even the son of a Nephilim if there were any left alive. It should be noted that Goliath was a giant (probably a Nephilim) and giants lived in the middle east, Malta, Sardinia and North American until several centuries after the age of Christ..
