BELIEVE it or not - but you simply have to watch it.

Incredible footage has emerged of what a group of Russians claim is the remains of a mangled alien.

The Sun reports the lifeless "body" was found in snow in the Irkutsk region of southern Siberia following reports of a "pink and blue glowing object" which crashed from the sky.

The "extra-terrestrial" appears to have lost a limb.

Even the country's Emergencies Ministry staff have investigated the incident after investigators said no aircraft were reported in the area.

Search and rescue teams found no evidence of an aircraft crash.

The strange clip of the discovery has now been seen by nearly 1.5 million people in the two days since it was uploaded on April 17.

So is it a fake? "Why do all aliens have to be naked?" one commentator pointedly asked.

"FAIL. Sorry...so fake," another wrote.

But the same writer was quick to qualify her comments.

"Do aliens exist? Certainly ... I believe they do. But not in this video."
