For the sake of argument, let's pretend that bigfoot is real. Now what? Until we get some real, actual scientifically verifiable and hard evidence to prove this "knowledge" we're still suck at square one - so absolutely nothing has changed in the slightest. We have no way to place bigfoot's location in the primate/hominid family tree because we have no DNA to analyse, we have no way of charting bigfoot's evolutionary history or migration patterns because there's no fossil evidence to study, and there's no way of convincing anyone else that bigfoot is real because we have - you guessed it - no hard physical evidence. So, what now?
