UFO Saved Earth from Destruction?

On June 30, 1908, there was a sudden, violent explosion in the sky over the Tunguska River in Siberia. The blast, 1,000 times more powerful than the atomic bomb dropped on Hiroshima, leveled 830 square miles of forest.

To this day, no one knows exactly what it was. Countless possible explanations have been put forward over the decades: a meteor or comet exploding in the atmosphere, a passing black hole, a falling chunk of antimatter, a scientific experiment gone horribly wrong, and the ever-popular UFO crash.

One Russian scientist takes this last theory to an entirely new level:

According to The Sun, Dr. Yuri Labvin, head of the Tunguska Spatial Phenomenon Foundation, has found quartz slabs with strange markings that he thinks were part of a UFO control panel.

He made the discovery near the site of the so-called "Tunguska event" -- a massive and so-far unexplained explosion that devastated more than 100 square miles of Siberian forest in June 1908.

Dr Labvin claims the slabs provide evidence that a spacecraft deliberately crashed into the meteor to prevent it slamming into Earth and wiping out life on the planet.

Does Hallmark make a "Thank You" card for that?
