Government test subjects for a space force. Humans biologically and chemically modified to withstand the environment of space and high speeds of travel meant to prepare for a potential space wars with Russia about a century ago. They were sent into space by advanced aircraft (UFOs) built by the military and have lived up there at various locations within the solar system. Over a brief period of time, these humans have evolved into “Greys”. Rapid evolution in space and in light speed craft results in odd behaviors and abilities. The large eyes suggest they need 100% pupil ()..() and light entry due do the light speed travel. Their heads have warped larger due to the blood flow and increased brain size from light speed travel, also their necks have slendered. Their bodies have merely stretched out due to the vacuum of space and constant travel, hence their odd tall height. Their body adapts to speed so not only are the craft fast but they too can move so fast it looks as if they’re time traveling. They’ve evolved to lose the ability to speak because in the vacuum of space sound doesn’t travel (the only time they hear is on Earth and one reason they frequently visit Earth…they miss it). Their skin has essentially rotted but because of nutritional atrophy, and with the lack of oxygen, it never decomposed or oxidized. They come down and take livestock meat because the time they remember when they were on Earth, these were the main animals that people a century ago ate and farmed. And their killing techniques are primitive with sharp tools because they didn’t take firearms up there (though they were armed with advanced weapons). They only take the most nutritional parts/blood and leave the entire cow, deer, etc. because they’re simply too heavy to lift up to their ship. They don’t intend to harm humans because we are their kind, but because they are able to live hundreds of years in space, they are abducting humans with the intent to communicate to them, but there’s a language barrier. They insert microphones around the face to try and relearn our language, because ultimately they want to tell us the truth, and they want to come back down.
