Grays and humans?

COuld homosapians (humans) and grays be related or decendants off some kind.

Scientists now believe that evolution is a random and uncontrollable process!!! Mabey, in that case how could a gray and human look alike, with out the anicient astronaught theory being true and they did breed with us!!! Or mabey we could have originated, but for some reason got sperated etc you get were its going.

There has to be something there, unawise, the greys could not exsist.

I think a similar shape would evolve on other planets, because its efficient. But the grays are kinda like bugs, i think they use bug dna.
