We have not always been alone. Since the Genus Homo, the Human animal, evolved in Africa we are but one of many. At one point in time Homo sapiens shared the planet with at least three other species of Humans and probably more.
We were all intelligent tool makers and fire users and we probably all used language and had customs and rituals.
Who knows what we lost with the loss of our fellow species? What music, art, dance and creativity would they have had? What different thoughts and insights?
We are not even the most intelligent. The Neanderthals had considerably bigger brains than us – despite us portraying them as ignorant and stupid. Perhaps they were just too kind?
We’ll never know what we have lost because the last Neanderthals met their end just 30,000 years ago.
I wonder what religion would have made of many other species of intelligent Humans? Would they have been accepted as being made in God’s image? Or shunned as works of the devil?
It would certainly throw a spanner or two into the works wouldn’t it? Just as if we encounter aliens who believe in different things.
