If that chance is 0.000000000000000000000000000000000000000000001% per galaxy, then there are thousands, no millions of planets with life.
There are more galaxies like our Milky Way galaxy (which already has billions of stars) than there are sand grains on earth….
That’s the fun of playing with big and small numbers.You can’t really contain it. If there is indeed only one form of life here on Earth, I would lose (almost) of my unbelief and believe in the Almighty.
It is also just what your life noémt of course.That is another earthly way of looking.
Well, the only intellectually honest answer to this is:
We have no idea of it.We still don’t know exactly how life originated, or we could simulate it. We have an idea, but certainly we are not.
As long as we do not know how life originated, we also do not know how likely the chance is that it happens.
Furthermore, we cannot even really see the planets and study the nearest star, Alpha Centaur.How can we then investigate whether there can be life?
Finally, we still have no watertight and conclusive definition of the question “What is life?”.So how can we calculate the probability that there is life somewhere?
And as long as we cannot do THAT, all speculation is completely irrelevant.
Right away… I SEEM to be particularly unlikely that we are alone in the universe.But that too is irrelevant.
At the moment, only data is about life on 1 planet, so extrapolating is impossible.There is an idea about life must have arisen, but the full circumstances are not yet known, so we cannot give any value to the chance of life, we only know that it has already happened at least once.
I do believe in extraterrestrial life through the scale of the known universe and because the earth is not so exceptional. It remains a belief and what we have to imagine in what life might look like is far from clear.
I also assume that there will be no contact with intelligent extraterrestrial life in the next hundred years.
Decision: Since we cannot say anything productive about the possibility of extraterrestrial life, there is a chance that the Earth is the only planet where life is.
I doubt the proposition is correct.The question suggests as if life on other planets exists anyway but that we have not yet been able to determine that.
Now I think there will be life outside of the Earth.Whether there are more complex life forms such as eukaryotes (where plants, animals and fungi belong) is again more unlikely. On Earth, it also took many billions of years before eukaryotes formed from bacteria and archaeots, and that under very favourable conditions.
The chance that intelligent life exists is even smaller.Intelligence is not a necessary and logical step in evolution.
It’s almost impossible actually.We see outside life as animal species such as humans, while outside Earth can also be plants and cells! Bacteria are already found in the space, which makes the chances of life VERY large. (Because bacteria even fall under living things) What kind of life there is to be found, we just don’t know yet. But it continues to live.
Also, the universe is infinity and we don’t know what’s going on for a long time. We don’t know all the planets and stars for a long time.So in an infinitely large something, the chance that we are only alive is very small. I still do not believe in the beings that resemble people, but I do believe in outside life. Just because it is so wide and because it is almost not avoidable.
Yes, there is a chance; I consider the odds are even great.People have quite a tendency to think, or to think magical. The majority of the world’s population still believes in magical entities and spirits and banshees, forest Spirits, Sinterklazen, paradises, Hellfires, Easter hares and thousands of gods and God and all sorts of eternal life after death and you name it- We are only just as intelligent enough to be able to determine with difficulty that we are only barely intelligent-and thus: magical thinking, belief in dream worlds, illusions and hallucinations and extraterrestrials that are all too often remarkably human, far too human..
This question is also misleading and insincere-we “know” not at all that our all-in-universe is “unlikely”, but because of the question it is brought to be a fixed fact-and it is certainly Not.There is a comparison ( Drake equation) that seeks to calculate that chance, but that has so many totally unknown factors, which actually says nothing at all.
Here is the piece from the Wikipedia article explaining the (justified) criticism of Drake’s equation clearly:
If the equation of Drake says that there is much intelligent life in the Milky Way, why has this intelligent extraterrestrial life not yet been made known?
According to some researchers, Drake’s formula is only thinking and the value is actually nil.Of most factors in the formula is still unclear what a realistic value is. However, for an estimation of the first factors (such as the pace of star formation and the percentage of Earth-like planets in stars), more and more measurement data is available by the increasingly sophisticated observation instruments on earth and in space . But especially of the last four factors is not known at all and that will not changein the foreseeable future either.It turns out that for the emergence of life an incredible amount of situations and conditions must be exactly aligned.If only one condition is not fulfilled, then no life arises.
Whoever thinks that there is life elsewhere, and if that reasoning is based solely on the quantity of stars, complexity does not understand.
I plant a seed in the ground and ask someone what it takes to change that seed into a tree.I see how people only come to atmosphere, soil, nutrients, sunlight and water with their thinking. If you have already succeeded, someone understands that the electromagnetic frequencies present in the Biotope also play their part. It comes down to the fact that a whole universe was needed because seed to create a tree. When you use the analogy of a number lock on the “BEGINNING” to the tree, you get so many different combinations that it takes a whole universe, to gain 1 life as we are humans.
Now, I don’t assume that we are the only life, but the next time you look up, understand what was really needed because living there to get, rather than just the quantity of stars.
You can’t exclude that opportunity.The problem is what we are talking about. The chance that our planet is the only one with life is extremely small. The number of planets is so immense that even with a chance of 1 in a billion there will still be millions of planets with life. Another story is intelligent life. That chance may be 1 in million, but there will be at least a few dozen. Then there is still the question of concurrency. Will there be dozens at the moment or are we the first, the last or the middle that contains intelligent life.? We will never know because the distances in the universe are too large to allow meaningful communication between intelligent species.
