Something Bizarre Happened in Siberia. What Was That?

In 1908, something bizarre happened in Siberia. On June the thirtieth, at seven AM villagers in Eastern Siberia saw a giant luminous sphere flying through the sky. It was approaching with a deafening roar that sounded like thunder. A couple of seconds later, an around forty-megaton explosion occurred. Such impact can be compared to the detonation of two thousand nuclear bombs. The blast wave was picked up in various locations all over the world. The forest at the explosion epicenter was immediately set on fire. Most trees within two thousand square kilometers were fallen. However, some of them remained upright for some reason. At the site where the alleged meteorite fell, there was neither a crater nor fragments. How could such a powerful explosion leave no trace?
