Jews might even be the aliens in question. I have a schizo theory that Jesus is actually just a weapon used by them in order to get people to be blindly accepting so that way they'd accept their secret oppressors(Jews) too. By pretending to be on everybody's side, they can use their power and influence to slowly replace the world. A slow but effective process for alien colonization.
If they had the advanced technology to go through time, they'd just send like some AI smart "virus" or something throughout the universe to perform the colonization for them. Like, maybe the whole christ virus thing is happening on other worlds. Where they just ZOG out other lifeforms with indoctrination and other forms of mind alterations to get other species out there to join some interstellar "alliance"
But it wouldn't even really count as an alliance imo, just the same copy paste ZOG zombie in a different alien body.
