BACTERIA a single cell organism of life.
To look at bacteria with the intention of finding out who we really are on this planet is something we could do research on because the article above will open your eyes to our time of life existence.
We are told dinosaurs lived 65 million years ago but how long did they thrive on Earth? 160 million years but they went extinct.
Mankind have been here about 5 million years with some of our relatives species have gone extinct.
I will say this is theory of mine which is my belief that within the last 300 million years one or more kinds of humanoid lived on Earth and have either left this planet or are still here. Because of bacteria evidence and seeing non human humanoid spirits inside human looking people.
