Although it's only one part of the answer, we have come another step closer to solving the question of how life originated. Two necessary molecular ingredients of DNA and RNA have been confirmed to have originated from outer space.

Radivoje Lajic thinks aliens don't like him. The Bosnian man says his home has been hit by meteorites no less than five times. He took the rocks to experts at Belgrade University, who confirmed that they are the real thing.

Still, Lajic seems sure this isn't just a coincidence.
