Roswelliens

The Roswelliens are a strange race, they technically were the first to officially make contact with earthlings...well not humans specifically but earth cows. Thinking they were the dominant species at the time, since Cows did nothing but eat, sleep and poop. Had males brought to them all their needs cared for by these human creatures, when the discovery of the hamburger was made by the Roswelliens they thought humanity had finally revolted. They found it to be quite the spectacle, they then began to abduct humans, learning all they could, saving their dna and letting them go safely and unharmed.   That is until one of their research ships crashed in Roswell, New Mexico. In the middle of a human military exercise. This was the first time the aliens contacted humanity and it was the coming months that humans set the record straight. The Aliens now deemed Roswelliens provided some insight in exchange for the new knowledge received. Which allows humanity to advance their own technology at the time.
