Ancient aliens

I love that with the Alien franchise that there's actually a slight possibility that creatures like the Space Jockey and the Xenomorph could be out there in the vast expanses of the universe. Like in Prometheus how Hollaway and Shaw discover all those hieroglyphs throughout different cultures. There's a lot of little hints in ancient civilizations records that point at the possibility of alien life. Thats one cool thing about the franchise is that there's a possibility that things similiar found in ALIEN could possibly exist. So there's that sense of reality that we can suck in from the films.

I think that 10 000 BC indirectly hinted towards ancient aliens
