Alien hunters are abuzz with theories after the sighting of what they claim is a UFO passing over a volcano in Mexico. UFO Sightings Daily even speculates that the craft was the cause of the eruption shown in the January 3 footage of the Colima Volcano

In the grainy, black-and-white video, a volcano can be seen as it begins to erupt, spewing out white light into the dark sky.

About 5-seconds into the footage, a flying object appears from the right side of the shot, travelling right in the line of the eruption.

The volcano continues to go up in lava and smoke for the next few seconds, and the 'UFO' flies behind the outburst, passing through to the other side.

Then, the object flies out of view, and the volcano continues to sizzle for another few seconds before erupting a second time.

According to Scott Waring, editor of UFO Sightings Daily, the video has captured the moment a UFO 'transports' someone to an underground base.

'This long UFO was caught over Colima Volcano on Jan 3. The UFO passes over and through the lava shot up from the mouth of the volcano,' Waring wrote.

'As it gets above the mouth, there is a bust of light and all goes black. The UFO then flies away.

'I believe that as the UFO went over the mouth, it transported someone or something to or from the underground base below the volcano.'

Other alien hunters had theories of their own.

'Wow. As if it had a preconceived notion of the arruption [sic]. I think it leans towards refuelling as opposed to the underground base theory,' one user commented on the UFO Sightings Daily post.

One conspiracy theorist suggested that visiting aliens might even be envious of flashy Earth technology, and drag-racing cars that are the 'ufo's of earth.'

'remember mr. waring, the ufos like planet earth because no matter how fancy the aliens are, there are no 56 Packard Caribbean's on mars 'not much of their stuff is as bizarre as that earth automobile,' the anonymous user comments, quoted as written.

'they probably wonder about racing cars tooo, those dragsters at night, look at that light show of those NHRA ddragsters. that's the ufo's of earth, not spaceships!! the aliens know about the drag strip in phoenix thatds why they showed themselves as ''phoenix lights. aliens like some earth people but maybe not others.'
