A group of physical unknown beings who are not originally from The Solar System who Humans would fraudulently disguise their existence, tricking the general public of their whereabouts to imprison as many species possible on Planet Earth, and Planet Mars making it appear they were able to kill people if encountered. This was a blatant media lie, they were not in the Solar system to attack living beings.

They say these beings would observe, and do research on Humans like autopsies during planetary visits to study and make Human contact.

On Jan. 2015, their existence was finally revealed worldwide, and Humanity killed itself because of the fear God wasn't real anymore was the ventriloquist spoken government fake outer world concept forced.

This led to the downfall of The Human Race in future years to come. All world government still deny their existence scientifically to current date, while Humans continue to also deny their communication contact in the 21st century.
An Alien is a being who flies a UFO, and has an ability to help develop a species, but Humans on Planet Earth always attacked these types of benevolent groups to gain their powers and abilities without their permission or blessings like the U.S. military did in Roswell,NM during 1947.
