The theory that life spreads throughout the universe as DNA which travels via meteors. It implies that life on earth was seeded from a different planet.

The theory is not held in high regard due to a number of critical flaws. For example, DNA would not be able to survive for the long period of time it takes to travel from one astronomical landmass from another, especially given that it would be subject to the extreme temperatures and radiation levels of deep space. Furthermore, there is no real evidence supporting the theory, and most believers simply point to humanity's ignorance for how life may have otherwise started on earth.
