What do you make of the UFO captured on video in the Colorado sky?

We don't know exactly where this took place, but at the very least we can tell it was near the mountains.

UFO's are rare and mysterious things, but in today's world, it's easier than even to capture a sighting on video. Still, most UFO sightings aren't usually extremely clear --which is the primary reason why they remain unidentified and very mysterious.

In this case, the unidentified object appears to float like a balloon, slowly drifting to the ground and out of sight. So is it a balloon, or are we witnessing an alien landing? You be the judge.
