14. A Mysterious Alien Spacecraft Explosion
In 2014, Russian researchers began working in Siberia, claiming to have found an extraterrestrial device, near a well-known explosion site.
Even to this day, scientists aren’t sure what blew up in the sky over Siberia that day, but theories were released that it was a large asteroid. The Tunguska incident exhilarated hundreds of square miles, and the effects are even visible to this day.
Around the same time, reports began to be made that there was extensive evidence of alien activity near this area, but this was never confirmed or sustained.
A few months later, a team of Russians set out to confirm that there were no remnants of spaceships, debunking this theory.
