An interesting UFO sighting has surfaced from Colorado Forest, but while some see something extraterrestrial, other affirm it is nothing more than a bird.

In the video below, a photo can be seen taken on July 28, 2013 over Colorado Forest.

As the video zooms in, a shape zooming by the camera can be seen.

The video goes on to proclaim that not one, but two UFO sightings is seen in the photo!

Since being uploaded on YouTube, the UFO sighting video has garnered more than 30,000 views, with a diverse set of reactions.

"These things are in the Bible. They are called the Nephilim. They are a hybrid of the fallen angels and humans from thousands of years ago, and they are returning because Jesus is coming soon," writes Ryan Wilson regarding the UFO sighting.

"Bugs... doing what they do...flying," says KYoss68.

In the video, the uploader proposes that the UFO sighting can be confirmed by pinpointing the rocket and rudder of the image on the right.

At the same time, it also appears to be a type bird, fluttering its wings as it flies across the camera frame.

So what do you think? Is this a true UFO sighting, or an insect or bird? Or, is this too vague to confirm one way or the other?
