Summary: You would think by now after 50 years of looking for Bigfoot we would have some good vidence. The videos are weak, the trace evidence is weak and the audio clips sound a lot like people howling and/or wolves or dogs. With aliens, we understand they are most likely somehow one step ahead of us. They aren't from Earth. Unless Bigfoot is an alien we should have evidence by now and we don't have DEFINITIVE EVIDENCE yet. WHy...I'll explain
