"They exist, but I haven't seen them," Obama said of aliens
on Saturday, adding cryptically that they "are not being held in (the defense facility) Area 51."
The comment quickly gained traction and made headlines around the world. The uproar has now prompted Obama to post a clarification on Instagram .
"Statistically, the universe is so big that the odds are good that there is life out there," he writes, continuing:
"But the distances between solar systems are so great that the chances of aliens visiting us are low, and I saw no evidence during my presidency that aliens have contacted us. I promise!"
