Former President Barack Obama set off a wave of online speculation over the weekend after appearing on Brian Tyler Cohen's podcast and fielding a question about aliens.

Former President Obama said he did not see evidence that aliens “have made contact with us,” after sending social media abuzz by saying aliens were real on a podcast over the weekend.

"I was trying to stick with the spirit of the speed round, but since it’s gotten attention let me clarify," Obama explained on social media.
