Space entrepreneur Robert Bigelow strongly believes that aliens are living among the people. Bigelow said that aliens have visited Earth and decided to migrate here.

A billionaire space entrepreneur named Robert Bigelow has surprised the public by his statement last Sunday on CBS "60 Minutes" show. Bigelow smartly answered a question, "Could intelligent alien life really exist on Earth and we wouldn't know about it? With a big YES they are among us," LiveScience reported.

According to Mach, Robert Bigelow is the founder of Bigelow Aerospace who believes that humans will soon leave Earth, and aliens will take over. "There has been and is an existing presence, an Extraterrestrial presence," Bigelow said during his television interview.

Meanwhile, it's not only Bigelow who has the belief in the presence of aliens on Earth. It is because polls results during the past decades have shown that one-third of the people in America agrees with Bigelow. They believe that aliens from other systems of the universe are cruising out skies, visiting Earth and sometimes decided to stay here.

The proofs are the videos of alien sightings like in the New Mexico desert and other 10,000 more UFO sightings reported in the U.S. annually. Seth Shostak, Senior Astronomer at the SETI Institute said, "Obviously, I think the aliens are really out there. Could they come here and be buzzing the skies and occasionally entertaining Bob Bigelow by visiting him. It doesn't violate physics, but is it likely?"

Bigelow also added during the television show interview that his grandparents have spotted a UFO on a canyon road while outside Vegas. He further stated his strong beliefs in aliens and said that they are everywhere.

However, even though 54 percent of Americans believes that there is alien life and life is capable of existing beyond the stars, there's no concrete evidence yet to prove that aliens are here. Despite the thousands and millions of sightings in the sky which are mostly mysterious lights, there is still incontestable and feeble proof of the aliens as Earth visitors and immigrants.
