Hey there Kenny, the theory of evolution is the closest we can come to trying to make sense of our origins as living beings. It still sounds fantastic though and will remain a theory.
Nevertheless, here we are as people on earth, with far more in common than different. Therefore naturally we should see ourselves more as brothers and sisters than as alien to each other. Especially now that we have shrunk the planet to a global village. Respect for all life should be our priority, though we have not reached that level yet, or if we did once, we have lost it again. Let's be the best version of ourselves.
