OK, here's the facts people....
...once upon a time, the earth was a very warm and wet place. One day, an alien was flying past earth and had to take a shit really bad. So he parks his alien ship down on earth, and takes a big crap in one of the stagnant pools of warm water. Then he gets in his alien ship and goes back to Zanar-5. Meanwhile, his alien poo was brewing in the primordial soup of that warm pool of water, and the bacteria contained within evolved into intelligent life forms that continued on to dominate the planet. The end.
