Well, just thinking on how many different life forms that have sprung up on our planet alone would lead us to believe there or more lifeforms elsewhere.

I can just see it now.

We manage to get to another planet and upon landing someone yells out...

"YOU'RE LATE!"

But, they all sprang from the same very fundamental and primitive single cells. Life spent a VERY long time on earth, relatively, stuck in the single-cell stage before the first plants appeared, and a long time after that before the first fish appeared.

You have to get from non-living molecules to prokaryotes to have life. Then, you have to get past that nasty single-cell stage.

Life on earth is astounding.

Even if you get to tissues and complex organisms, plants, animals, the jump to actual sapience / consciousness is such a random direction to take.

I'll stand on my assumption that there is some form of complex (multi-cellular, multi-organ) life out there. That doesn't have to be life with what we consider a "brain." And I'll say the development of consciousness is unique in this universe. The next form of life is being created by humans.

Could be but probably not.

Numbers mean nothing.

Just because there are so many trillions of suns doesn't mean that the law of averages means anything......that's like sayin that you'll be able to find a grain of sand that can speak.

What are the chances?

Has to be. It sounds silly to suggest we are the only living organisms in an ever expanding universe.

That is possible and there is no evidence that suggests otherwise however there is places within our solar system that could support life based on what we know. Life is found at every extreme on earth whether it's at the very bottom of the oceans, deserts, Antarctica, volcanoes etc.

Keeping that in mind consider a beach and how many grains of sands there are as far as the eye can see, that's a lot but now consider how many grains of sand there are on every beach on earth. This is what is often used to describe how many stars there are in the unviverse, it's an incomprehensible number. The possibilities for other planets and moons that could support life as we know it is immense, there is most likely world's with identical conditions to here on earth.


The fundamental question is what triggers life and if it happened here why not somewhere else?

It's much larger number than trillions of stars, the largest known galaxy has an estimated 100 trillion stars. There is an estimated 200 billion galaxies with an estimated 72 sextillion stars in the observable universe. that's 72 followed by 21 zeroes.

72,000,000,000,000,000,000,000

Roughly speaking if you had one trillion dollar bills you would have a stack the size of one of the WTC towers. You would need 72 billion of those stacks to represent the stars in the universe, that would be a 100 story stack of bills more than half the size of the US. No matter which way you try and describe it he numbers are incomprehensible.

What's beyond the observable universe we'll never know unless you can break the speed of light, galaxies beyond that point are moving away faster than the speed of light..... The reason that is possible is because the combined speeds moving in opposite directions.

Why should that mean we can't observe them? Not enough time for their light to reach us?

Correct. Suppose light speed was 50 MPH. If you had car on either side of you and they both started going 50MPH you can look right and left and see each car, the driver of that car can look in the rear view mirror and see you. What they can't see is the other car becsue the combined speed of both cars moving away from each other is 100mph.

Fascinating, yes? This expansion is accelerating and the further away galaxies get from each other the faster they are moving away. Billions of years from now(or whatever it is) if an intelligent life developed they will look out at the Universe and see nothing.

Are you saying "Horton Hears a Who" isn't real?
