The description of “reptiliandude” is that the “Kayeen” (cf. Cain) are a humanoid alien species that messes with DNA (they have corrupted their own to a point they need to use other species to repair their own) and has evil predilections to abuse children. They have a technology that allows them to “overwrite” the brains of humans with their own. Either partially (demonic possession) or fully. (from before birth controlling the baby’s brain). Jesus was able to drive these evil entities out.
