The life generation in SE is based upon rough statistical probabilities.The principle of mediocrity says if there is one world with life, then there are probably many worlds with life simply due to the number of worlds in the universe and the same laws of physics applying everywhere.If it happened once, and we readily see amino acid and complex organic molecules forming in space, then it should be expected that in the right conditions life should exist in such a large universe.Plant coloration is loosely based upon ideas likeIf you do not like life spawning then open up your main-user.cfg file and edit the life probability settings to fit your tastes
