5 Reasons we are (probably) completely alone in the universe
A government funded program called SETI, or the Search for Extra Terrestrial Intelligence has been listening for intelligent life in the universe, with their radio telescopes, for past 50 years, but so far NOTHING has been found.
Is it possible that the hundreds of scientists around the world that are looking for intelligent life are on a futile mission to nowhere –
because there is actually NO OTHER intelligent species in the entire universe –
The shocking answer is – YES. I’ll explain why.
There are more stars and planets in the universe than all the sands on all the beaches of the world. How is it possible that we could be the only intelligent life out there. I am talking about intelligent life, not just any kind of life.
I think ordinary life is probably everywhere in the universe, and I predict there is life within our own solar system. See my other video on this subject. Intelligent life is a completely different animal, no pun intended, than simple forms of life like bacteria and viruses. There is a good chance that there is NO other intelligent life…and here are 5 reasons why:
Number 5, earth has a very large moon compared to its home planet. And this moon was formed due to a colossal impact with another planet early in earth’s history. This collision caused the earth to almost completely melt, which led to molten iron being pulled to the center of the earth. The reason this is important is because it is the flow of this iron that allows earth to have a relatively strong magnetic field. Without this field, life would not exist, because cosmic rays would have wiped out any early life.
The moon also gives the earth orbital stability, and has absorbed potential meteor impacts that would have otherwise devastated earth. Such massive collisions are probably rare in the universe.
Number 4, there was a massive extinction event that occurred on earth about 500 million years ago – long before the age of the dinosaurs.Over 80% of all life on earth was wiped out. …but luckily for us, a tiny creature less than 2 inches long, called Pikaia, which had a backbone, survived.
This creature is the ancestor of all animals with a backbone – including us. If it had not survived that extinction, we would not be here.
Number 3, for over a 100 million years, mammals were small mousey shrew-like creatures that lived under the shadow of the dinosaurs. They only came out at night because during the day, they would be easy prey for the huge dominant species of the day – dinosaurs. The only reason mammals dominate the earth today, and by the way, we are the most dominant of the mammals, is because the dinosaurs were wiped out by a huge 6-mile-wide asteroid that fortuitously killed our overlords, about 65 million years ago. It if wasn’t for that lucky asteroid, we wouldn’t be here.
Number 2, arid conditions hit East Africa millions of years ago. It didn’t happen anywhere else, but only in East Africa. It so happens, that living in east Africa at that time were tree dwelling apes, that were forced to leave the trees and journey into the grasslands below to find food to eat. Not only did this force these primitive primates to stand upright, which freed up their hands for using tools, but it also forced a huge increase in brain size… Because these animals needed a much bigger brain, and higher processing power to help them find food.
We are a direct descendant of these primitive apes.
If these arid conditions had occurred anywhere else on the globe, it would not have resulted in us.
And now the number 1 reason: There have been millions of species of animals that have lived on earth.
In fact, many more animals have gone extinct on earth than are living today.
But out of all those species of animals that have evolved nearly every feature and trait that you can think of….only ONCE,
that’s right, only ONCE has the trait of higher intelligence evolved.
We are the only animals that have ever lived on earth over its 4 billion year life-span, that has evolved to be super intelligent.
Intelligence is by no means an inevitability in the course of biological evolution.
If it was, then there would have been many such evolutions of highly intelligent species who would have inhabited the earth over its 4 billion year life span.
Had we not had many strokes of luck and multiple events going our way, we would not be here at all.
Thus, it is quite possible that we may be listening with our radio telescopes to complete silence because there is no one else out there. …other than us…imperfect humans on a tiny rock…orbiting an unremarkable star…in an ordinary galaxy…in a generic point in the universe. All we have is each other.
