It's all pseudoscience/"amateur" history though. As far as I know, no experts take it seriously.
I grew up in a religious household and even as a kid, I couldn't help but draw parallels between current technology or science fiction and religious icons or events, before I even knew the name for that concept.
For example, in Islam the Quran mentions a steed, made of light in some tellings, whose step takes it to the farthest point within its sight.. [1]
A craft that travels at/near the speed of light?
They also have the concept of seven skies, or heavens; could it be seven planets known at the time?
What about the different orders of angels in Christianity, flying beings (again made of light in some versions) each having an increasing number of wings?
And of course there are already adaptations of the story of Atlantis as an alien mothership that crashed into the ocean and eventually sank.
In any case it's fun to think about.
