VIDEO showing a smoking crater next to a motorway has lead to speculation it could be a UFO crash site.
Online theories have ranged from a crashed spaceship or a meteor falling to Earth.
It happened on January 17 and the video was uploaded to YouTube the next day, before racking up tens of thousands of views, Dailystar.co.uk reports.
One YouTube poster said: “Looks like a UFO landed and took off before anyone could see, leaving a crater.”
Another viewer said: “It’s a burning hole. Does not look like an impact to the earth as there is no debris.”
It is not the first mystery burning hole to have been found in Mexico.
These holes can also be used by gangs to burn bodies, weapons and drugs.
Others believed the crater could be linked to the increased sightings of meteors recently.
A third viewer stated: “Could be related to the meteor incidents we have seen in Michigan.”
However, officials have said that no meteorite fragments have been found nearby.
Meteors regularly bombard the Earth, but most break up in the atmosphere or land in the sea rather than leaving an impact crater.
Those that do break up will sometimes leave fragments on the ground, which people are keen to collect.
Last Tuesday, a bright meteor briefly swept across the sky over parts of the US Midwest and Canada which caused a powerful explosion rattling homes and astonishing onlookers.
The official explanation from experts such as NASA was that a meteor had entered Earth’s atmosphere and burnt up upon arrival.
Just after Christmas in the Urals region of Russia, night was briefly turned to day after a meteor is believed to have exploded in the atmosphere.
Russia has seen one of the worst meteor incidents in recent years.
In February 2013, an unknown 19-metre meteor came from nowhere to explode in the sky above Chelyabinsk, Russia, with the force of 500,000 tonnes of TNT.
And the energy released shattered glass on hundreds of buildings and more than 1,000 people were injured as a result.
