19. A Secret Agreement Between The Knights Templar And Aliens
Going deeper down the rabbit hole we find the possibility of a human colony run by aliens on a planet that only receives twilight.
Duncan Lunan, a Scottish sci-fi writer, created the theory of an alien-run human colony on another planet where dusky light is received and food is genetically modified by the aliens which causes the colonized humans to have an unusual skin color.
He adds that the Knights Templar made an agreement with the aliens to use wind and water powers and methane digesters to charge up portals that could allow the humans and aliens to pass between different worlds.
Amidst all the portal traveling the Green Children would have got lost and ended up in the pit from which they emerged.
