Americans unleash speculation that Pentagon's UFO report proves #AliensAreReal

"The universe is a pretty big place. If it's just us, seems like an awful waste of space," wrote Carl Sagan in the 1985 book Contact. That has proven to be a topic the Pentagon has been investigating.

It was just three years ago that former US Naval officers reveal a 2004 encounter with possible a UFO in an extensive New York Times interview.

“I would hope somebody is checking it out!” physicist Neil DeGrasse Tyson exclaimed in a CNN interview. “I hope there’s a program from our Defense Department to make sure they do not pose a threat. Sure enough, that’s what the program was.”

This week, the Pentagon released new footage of unidentified flying objects, which are technically just that, not necessarily space aliens trying to invade. But 80-year-old former Senate Leader Harry Reid warned: “The U.S. needs to take a serious, scientific look at this and any potential national security implications. The American people deserve to be informed.”

Reid's state houses the air force base Area 51, speculated by science fiction books, films and television shows to house evidence of UFO technology and extraterrestrial biological entities.

Americans responded to the news Tuesday by going full Fox Mulder and proclaiming "the truth is out there."
