Despite our advances in science and space exploration, it seems that we have investigated only 4% of our universe. By way of illustration, this would be like all of mankind living in Australia while knowing absolutely nothing about the rest of this fine planet.
In such a scenario, if I were to make an announcement (still bearing in mind that no one has ever ventured outside of Australia) that there is a possibility that creatures are living in another country far away, most people would probably agree with me. But if I were to describe one of these creatures as looking a little like Homo sapiens, but with longer arms, shorter bowed legs, and long reddish-brown hair covering its head and body, some people might say I’d been watching too many science fiction movies.
