NFL Prospect Tip Reiman Believer In 'Birds Aren't Real' Movement

Former Illinois football star Tip Reiman had the most memorable quote of the NFL Combine so far ... telling reporters he believes birds are not what they seem!!

For those who aren't in on the joke ... the "Birds Aren't Real" movement made waves a few years ago, when a guy named Peter McIndoe created a satirical conspiracy that winged animals are actually spy drones for the U.S. Government.

A bunch of people joined in on the troll job ... and now, it's even made its way to professional football.

Reiman -- who had 203 yards and three touchdowns last season -- revealed his allegiance with the movement on Thursday ... hitting reporters with several questions that support his stance.

"Have you ever seen a baby pigeon?" Reiman asked, according to Owen Riese. "How do we know that power lines aren't pigeon recharging stations?"

Some people think Reiman is actually serious ... comparing him to Aaron Rodgers, who's been known to rock a tinfoil hat from time to time.

But Reiman's take wasn't the only bizarre statement out of Indy this week -- Texas Tech standout Tyler Owens also told reporters he doesn't believe other planets exist ... adding some flat-earthers have a strong argument.
