I have read a number of answers to this question. All have answers like it helps us keep balance etc. . . But there can be a very fundamental reason. Humans evolved from apes. Our ancestors used to walk on on four legs. If we observe a four-legged animal, it walks moving its limbs alternately. So, can we reason that as we evolved from four-legged animals, we have still haven't forgotten moving our limbs alternately?
