What if humans are the product of mating that took place between extraterrestrials and primates? It would explain human/ape similarities, but also account for our differences. It seems like an incredible notion, but take a look at the following painting by Gary Soszynski.

Is it not plausible that we are an alien/ape hybrid? This could also account for the "junk DNA" found in humans. Some scientists believe that is the result of our extraterrestrial origin.
It's a deep rabbit hole filled with inter-species mating, genetic codes and alien DNA, but it comes back to one of man's most fundamental questions: how did we come to be here? What are we and what is our purpose? Who is our creator? God? Aliens? We can only continue to ask these questions and seek the answer through scientific inquiry and research.
