Now there has been another claim about the existence of Alience by US Army helicopter pilot.

He says, he have spent 92 days on an alien mothership claimed that humans "will find ancient alien ruins" in the universe soon, according to the UK-based Daily Express.

Alex Collier said that he "spoke to two aliens in the 1980s" and insisted that his encounter with the aliens was unique.

He further claimed that he was taken aboard their spaceship and had to wear a special belt so that aliens could communicate with him for three months.

According to Alex, the purported experience happened when he was playing hide and seek in a cornfield and fell asleep, only to wake up on the spaceship, the report said.

During a talk in Japan in 2007, Alex shared what the aliens told him about the universe.

"Our science tells us that there are 100 billion galaxies, but we are only looking at one dimension."

"According to the Andromedians, there are 100 trillion galaxies and every galaxy has life in it. We are far from being alone. The universe is vast ... we are just beginning to travel space and we are going to find ruins everywhere," the Express quoted him as saying.

"I once asked the Andromedians how technologically advanced we were, and (they said that) the United States Army is 400 years more technologically advanced than we think they are," he added.

The report quoted Collier as saying that humans are the only beings in the universe who use money.
