Do you believe in possibility of life in other galaxies?
The universes are crawling with life!
I dreamed I saw the silver spaceships flying, in the yellow haze of the sun
There were children crying and colors flying, all around the chosen ones
All in a dream, all in a dream, the loading had begun
Flying Mother Nature's silver seed to a new home...
I bet that, a technological civilization exists in our galaxy!! Trying to communicating with it though, is a different matter entirely!!
The Drake equation.
I am not sure about that. I can agree that some forms can exist in the Solar system. For example, some forms of life can be on the surface of Mars. This planet has water ( ice ) and some forms of life can be in that ice. So I guess in some time we will get to know it for sure.
Personally, I think that the chance is very high to find some forms of life ( even probably intelligent ) on these exoplanets. Moreover, some scientists claim that there are some planets that remind Earth. However, we should`t hurry with conclusions, these planets are too far and the only think that can remind Earth it`s the size of this Earth- alike planet.
The question that has fascinated me ever since I was barely a teen. My sister and I must have spent many hours discussing this. But back then it was done with hope and idealism, today we discuss it in a more calculating manner.
The Fermi paradox aside, I can guarantee life is out there, but we all know @robert55 specifically meant intelligent life, civilizations based on technology. To be honest, I'm not so sure there is, at least not in any significant numbers.
Assuming carbon based life similar to our own, there are so many things that would have to fall into place. Atmosphere, water abundance, seasonal variations, magnetic field and yes, even an abnormally large satellite affecting tides. Extinction level events throughout the history of an alien planet that allowed for the right species to survive and dominate would also play a role. But the list doesn't end here.
Any one factor by itself would not be uncommon, all the necessary factors for life like us to evolve could be almost impossible.
If I recall, there are a lot of Foundation fans here, funny that until his latter books, Asimov had an entire galaxy populated by Humans only, originating from a single long forgotten world. I remember even the plant life (with the exception of simple grass and shrubs) also shared the same origin. Perhaps then in the end, we may find out that we are a statistical anomaly, making it that much more a pity if we annihilate ourselves before we reach the stars
