Extraterrestrial DNA returns to earth to decipher the origin of human beings

Darwin's "the origin of species" explains how human beings evolved to what they are today, but it doesn't tell us how organisms came from the earth in the first place. Recently, a 13 minute video in Scientific American magazine provides us with a bold guess.

Germany and Switzerland have jointly studied the origin of DNA. Using DNA returned to the rocket for experiments, we found that DNA activity is still strong under the torment of atmosphere and high temperature. The fact tells scientists that the heat resistance of DNA is beyond our imagination, and the stability of double helix structure is very good.

Therefore, the origin of DNA of extraterrestrial argument came into being, scientists believe that the earth's human DNA is likely to be meteor impact on the earth, brought to the earth.
