The endless march of biological evolution seems to favor more and more complex and intelligent species. Current scientific theories believe life itself started as primitive single cell organisms and slowly advanced to multi cellular creatures. After countless millions of years, semi intelligent animals appeared on Earth and now Human Beings are the dominant species on our planet due largely to our superior intellect over plants and animals.

We are probably not the peak of the evolution of life in our Universe. It could be a fact that very, very extremely advanced machine based entities are the most sophisticated and powerful entities in reality. However, it should be noted we have absolutely no evidence that aliens extraterrestrials or supernatural eternals are real.

However, superior entities could remain invisible, unseen and beyond our perception. If we ever encounter extraterrestrials aliens, it is an almost certainty they won't be purely biological flesh and blood beings. We have to expect alien extraterrestrial life forms to be exotic and perhaps beyond our most grand and most bold imaginings.

Many scientists on Earth regard advanced machines or something similar to be the top and highest level of the evolution of life, but it's more than likely that the greatest alien extraterrestrial civilizations would be far, far beyond the notion of machines of technology. These extraterrestrials aliens might have moved from mostly biological organic in origin to highly developed artificial intelligence.

Yet their progress probably didn't end with what we consider possible. The aliens extraterrestrials likely made scientific discoveries we can't fathom at this point in time. In the final examination, the extraterrestrial alien masters of the Universe, who can't be questioned, are something more wondrous and infinitely stunning than what we can currently understand at this location in our technological journey.
