They have also argued that flattened trees show that 'two bodies entered the atmosphere. One exploded about five miles (8km) above ground, while the other hit the Earth where Lake Cheko is now.
The Tunguska event was a mega explosion, caused by an asteroid or comet, which occurred near the Podkamennaya Tunguska River in what is now Krasnoyarsk Krai, Russia, on June 20, 1908.
It is classified as an impact event even though it exploded in the sky rather than hit the surface with as a result that about 2,000 square km of forest was flattened. The explosion could be heard 1,200 kilometers away even atmospheric pressure was detected in Britain.
Now, Russian scientists deny the theory of the respected Italian team by 'proving' that the remote blue lake is not young enough to be a crater lake caused by the Tunguska meteorite reports Siberiantimes.
Furthermore, as only tiny particles of cosmic dust ended up on the surface it seems impossible that Lake Checko has been formed by only cosmic dust, besides if it was meteorite where are the other impact craters and the extraterrestrial matter? So if the Tunguska event did not cause the mysterious Lake Checko, what did?
About the Tunguska meteorite, in recent years many speculations have been emerged but the most likely theory appears to be that a celestial object was completely destroyed in the atmosphere by an alien race by using advanced technology before the object could have destroyed the planet.
