We're in it either way. My own theory: Given the varied races and languages on earth, it's unlikely we were descended from apes. Planted here on a bountiful world by various alien races who have developed a plan for 'ownership' of said world being:
Whichever race survives gets the planet. The bummer being the potential total wreckage of said planet in the process. This has nothing to do with the 'computer simulation' theory...but it's somewhat plausible nevertheless. (?)
I really liked the "math-sterbational" from ed1t. Great play on words.
