A scientist has revealed that aliens are real.
Dr Boyd Bushman - who used to work at Area 51 - opened up about his career in studying UFOs and alien life at the secretive base in a documentary filmed just before he died.
"With respect to the alien craft, we have American citizens who are working on UFOs 24 hours a day.
"We are trying to learn what to do."
The former senior scientist describes that the aliens we know of can be split into two groups.
"There are two groups of aliens," describes. "They divide them into two groups. It’s like a cattle ranch.
"One group are wranglers, and the others are rustlers – the stealers of cattle. The ones that are wranglers are much more friendly, and have a better relationship with us."
He describes the aliens as five feet tall and says that "one or two of them are around 230 years old".
He goes on to reveal that 'at least 18 operate with our facility'.
While their eyes and noses are different from humans, Dr Boyd reveals that they still have five fingers and five toes but they are telepathic mind readers.
"They're able to use their own voice by telepathy to talk to you," he reveals.
He also added that the aliens were dressed in dungarees so they could be grabbed when they started to float. source
