What about this, there are no aliens. In fact there is not one shred of evidence that points to any other intelligent life in the entire universe. E
ven if there were other intelligent life that could communicate with us, there is little chance either civilization would ever know of the existence of the other because of the vast distances i.e., the amount of time required for our radio or laser communication technique to travel between the civilitations. Most likely our civilization and theirs would exist and then end before we ever knew the other existed.
It is also possible that earth is the first planet to spawn intelligent life, somebody has to be first, why not us. Maybe we humans are the first life in the universe that has successfully gotten past the great filters which allow for basic single cell life but create almost impassable barriers to evolve all the way to intelligent life like Humans.
For instance, the leap cells made from Prokaryote cells to Eukaryotes cells. Without that leap 2 or so Billion years ago it is doubtful that any multicelluar or animal life would have ever appeared on Earth.
Or the moon; without the moon to stabilize the earth’s rotation there never would have been the long time frames of relatively stable environmental conditions which allowed for the evolution of life into multicellular and then to intelligent animal life.
Don’t get me wrong, I suspect that basic cellular life is most likely in many places even in our own galaxy. It would seem, at least according to our single data point, Earth, and extrapolate it; Life seems to have started on earth about 4 billion years ago, almost as soon as the young earth could support life, boom it was there. So I think we as a species, as we go out and colonize other planets/asteroids etc...etc..., we’re going to find that basic single cell life is going to be abundant but I doubt we humans will ever meet intelligent life anywhere because the great filters make it nearly impossible for basic life to evolve into intelligent life.
As far as we know, life evolving from single cells all the way to intelligence at our level has only happened once, and it took about 4 billion years to do it; until there is some kind of evidence that there is intelligent life elsewhere in the universe, that’s my story and I’m sticking to it.
It’s entirely possible for an empty universe, but I’m biased against that if only because of the nature of God.
Agree with the essence of what you are saying.
However... Saw something just the other day with good hard science behind it that said the jump from single cell to multi cell is a trivial hop. They were using yeast and results were pretty solid. That doesn’t get you to a room full of monkeys typing hamlet I totally grant you.
Complex organic molecules are common throughout the solar system and the rest of the galaxy. All you need to create them is the right mix of elements, a high pressure environment to contain and mix them, a constant heat source, and time. A lot of time. The big unanswered question is how to make the jump from the most complex organic molecules to the simplest living organism.
Unless and until we either (a) actually discover life somewhere else or (b) figure out how to make a living organism from scratch in a laboratory, we have no idea how common or how rare life may be in the universe.
It could be that the evolution of life on Earth required countless specific conditions and trillions of events all happening in exactly the right order and that the rest of the universe is entirely sterile. Or it could be that life is common anywhere there is a planet with water.
“In fact there is not one shred of evidence that points to any other intelligent life in the entire universe.”
Tucker Carlson and his government sources disagree.
But more to the point, how is it that you, and only you, have the range of knowledge, experience, mind power, etc., to make such a statement?
