Reptiliandude: My species is NOT from this world. Unfortunately, (but lucky for you) the theropods on this planet were beaten down by cataclysms on a continual basis. The negative mutations are evident in the fossil record as the number of digits on their hands became less and less in number. Five is ideal. Four is still workable, but time consuming. Three nearly a guarantee for failure, and two a death sentence, unless that creature has evolved with those with three into flight. It is curiosity, tool use, an omnivorous diet and the ability to carry things that results in advantages to those with lesser tooth and claw. Extra points if that creature ate psychedelics found while foraging during its social development. The dinosaurs on your planet adapted to their loss of digits by extending the fingers into wings, and becoming creatures of flight. My species discovered tool use and how to use weaponry much like your primates did, and so became creatures of FIGHT rather than flight. So while you are the result of a common ancestor of the apes, who left the trees and took to walking upright, my species; simply put, is the result of a common ancestor of creatures similar to your dinosaurs who possessed five digits and never took flight.

The information contained in DNA stretches all the ways down to the spin characteristics of sub-atomic particles. These vibrations create patterns which are considerably more complex than the simple on off switches used by ones and zeros in your computer language. This resonance is how a spider knows how to build a web. The communication of these sub-atomic particles instantaneously causes reactions throughout kindred space-time. It is one of the reasons why rice has so many more genes than a human being. It is because rice is more common in the universe than people. The so-called “genetic dark-matter” your scientists can’t make heads or tails of is simply those particles responding to disease on other worlds and preparing that particular species for the hitherto unknown possible emergence of the same on its own world by informing it through the ladder of its genes. When you extend your influence into space, you will discover that if a particular parent star goes nova and from its travails brings forth other smaller stars like your own, those worlds which form will have a closer connection through the co-particles to other worlds. Life then becomes easier to develop (and similar in form) because of that quality which the two dimensional plane brings up into this great three-dimensional simulation. As for “grays” they are quasi-synthetics built to withstand the rigors of the sorts of radiation which would mutate and kill life such as your own (and ours as well). They were developed originally to assist the self-replicating bots we have been using to mine asteroids and planetoids for millennia.
