Neil deGrasse Tyson Baffled By Demi Lovato's Claim We Shouldn't Say 'Aliens'

The singer believes it is an offensive label, and they instead opt simply for 'ETs'.

However, astrophysicist Neil deGrasse Tyson is a little stumped by their logic.

"So to be worried about offending them by calling them an alien, what is she thinking is going on in the head of species of life from another planet?

"I mean, I know it's very considerate of her, but really? Really?"

The 63-year-old went on to explain how he uses the term 'alien'.

He said: "When I refer to aliens - just to be specific - I always say 'space aliens'. And then, what we used to call aliens on Earth, undocumented immigrants, that's what the new term is for then, and I'm all in on that.

"So what that means is - if we all do that - the only invocation of the world alien is for creatures from outer space that want to kill us all.

"First, I don't care what they feel. Plus, why should I even believe they know English?

"So, yeah, I'm not all in on that. I don't get it."

The 29-year-old explained: "I think that we have to stop calling them aliens because aliens is a derogatory term for anything.

"That's why I like to call them ETs! So yeah, that's a little tidbit. A little information that I learned."

Opening up about the motivation behind their new show, Demi continued: "I have been a believer my whole life. And I just thought, you know, I'm in a position in my career right now where I'm dipping my toes into a lot of different waters.

"And this was just kind of a natural next step. I wanted to film everything that goes down when I go and search for these UFOs so that my fans can come along for the ride."
