In case you needed a reminder, yes we are in the year 2017, and yes there are people that think Earth is flat.
And not just your regular "Mad Mike" characters. Oh no, a number of celebrities in the past few years have come out in favor of the bizarre theory.
From basketball players to musicians, a number of celebrities are jumping on the flat Earth bandwagon. You'd hope that most of these aren't actually being serious but, hey, a climate change denier is currently President of the United States. Anything goes it seems.
So here are a few celebrities who, for one reason or another, have expressed the view that they think the Earth is flat. I'm looking forward to seeing what exciting conspiracy theory makes its way into the public mainstream in 2018.
Kyrie Irving is the celebrity that arguably started this recent bout of flat Earthness. In early 2017, the Cleveland Cavaliers' guard said he thought Earth was flat.
"This is not even a conspiracy theory," he said in February. "The Earth is flat. The Earth is flat. It's right in front of our faces. I'm telling you, it's right in front of our faces. They lie to us."
Irving doubled down on his beliefs multiple times. But in September, he claimed that the whole thing had just been a "social experiment", and he had spun the world "into a frenzy".
So, it was all just a joke? I guess. Haha. Very funny.
Sammy Watkins/Draymond Green/Wilson Chandler/Shaquille O'Neal
Irving may have been joking, but that didn't stop a number of other basketball players coming out in support of the flat Earth theory.
Los Angeles Rams receiver Sammy Watkins supposedly also believes Earth is flat, although maybe he was in on the "joke" too.
There's also Golden State Warriors forward Draymond Green, who said he didn't know if the Earth was flat, "but it could be".
And there's Denver Nuggets forward Wilson Chandler, who in February tweeted: "I agree with him" in response to a now-deleted tweet about Irving.
Who's being truthful? Is anything real? Is Earth really flat?! I just don't know.
