Aliens visited Earth, made contact with humans: US lawmaker

Aliens visited Earth in an otherworldly craft and made contact with humans, US Congressman Tim Burchett has claimed. He said he doesn't believe that they pose a threat to humanity. "I don't think we're at danger of this. I mean, these things exist...and they could've destroyed us with the blink of an eye, I just don’t see that," Burchett said.
