I've done some considerable thinking in the past about the idea of our intelligence being a modification or an addition to a previous mental and evolutionary state. I must admit that I never gave it much thought until I heard some ancient astronaut theories that grabbed my interest but I find it very plausible that our development could have been aided long ago.
On further research, ancient astronaut theories are supported by very weak evidence and mostly conjecture. And at that most of that evidence is not looked at in the context of where it came from, and is based on misunderstandings.
There is nothing plausible about the theories.
