Do you think there is life in other galaxies?

the probability is very high but still if there is no evidence we cannot really answer this question, all we can say is " it is possible" We have recently discovered that actually life can exist in the harshest and extreme environments which further increases the probability of ET.

I think that saying we're the only ones in the universe is extremely ignorant. there is so much of the universe we haven't explored and it seems nearly impossible that there are no other forms of life. I also believe that there will be more advanced life, less advanced, and probably life at the same stage as us

Yes, I would think at least some other life form is at our level of intelligence but i don't consider humans to be a very advanced civilization.

From a science perspective, I find it is best for me *not* to assume one way or another without clues or scientific evidence. That way, I won't bias any scientific research I read and can approach raw data or concepts with an open mind.

As a scientist I really don't like to guess at things... So I won't answer yes or no to this question. That being said some work has been done in this area. A fellow by the name of Frank Drake attempted to use observable data to form an equation to answer this question. Although Drakes equation looks at the probability of life in our own galaxy, we could (if it could be proved) use that answer to calculate the probability of life in other observable galaxies. The Drake equation states that: N = N* fp ne fl fi fc fL The equation can really be looked at as a number of questions: N* represents the number of stars in the Milky Way Galaxy Question: How many stars are in the Milky Way Galaxy? Answer: Current estimates are 100 billion. fp is the fraction of stars that have planets around them Question: What percentage of stars have planetary systems? Answer: Current estimates range from 20% to 50%. ne is the number of planets per star that are capable of sustaining life Question: For each star that does have a planetary system, how many planets are capable of sustaining life? Answer: Current estimates range from 1 to 5. fl is the fraction of planets in ne where life evolves Question: On what percentage of the planets that are capable of sustaining life does life actually evolve? Answer: Current estimates range from 100% (where life can evolve it will) down to close to 0%. fi is the fraction of fl where intelligent life evolves Question: On the planets where life does evolve, what percentage evolves intelligent life? Answer: Estimates range from 100% (intelligence is such a survival advantage that it will certainly evolve) down to near 0%. fc is the fraction of fi that communicate Question: What percentage of intelligent races have the means and the desire to communicate? Answer: 10% to 20% fL is fraction of the planet's life during which the communicating civilizations live Question: For each civilization that does communicate, for what fraction of the planet's life does the civilization survive? Answer: This is the toughest of the questions. If we take Earth as an example, the expected lifetime of our Sun and the Earth is roughly 10 billion years. So far we've been communicating with radio waves for less than 100 years. How long will our civilization survive? Will we destroy ourselves in a few years like some predict or will we overcome our problems and survive for millennia? If we were destroyed tomorrow the answer to this question would be 1/100,000,000th. If we survive for 10,000 years the answer will be 1/1,000,000th. When all of these variables are multiplied together when come up with: N, the number of communicating civilizations in the galaxy.

It is quite a big stupidity to say there isn't life elsewhere. In fact, recently, a planet, about 600 light years away from earth has been discovered which has conditions very similar to that of earth. So it is quite possible for life to be present there. And of course there are so many undiscovered parts of the universe. We have no idea how and where life may exist and in what form. And as for the question of them being more advanced than us, all we can do is guess. For, if there is life elsewhere, we have not yes been able to establish communication with them. So it is quite difficult to tell about that. It may happen such that life at one place is more advanced than us whereas life at another is less advanced. Hope this helps. Keep smiling! =)

Nope. Saying that there "must be" life in other galaxies is extremely ignorant, and shows total scientific illiteracy. There is no evidence to support such a claim. It comes straight from the arrogance of man to assume that just because we exist, then other life "must exist" also. I don't have to rely on guesses or imagination. Being an expert astronomer I can tell you that the Fermi Paradox virtually guarantees that such life does not exist. And even if there is a microbe in some distant galaxy at the furthest reaches of the universe it it totally undetectable.therefore it essentially does not exist as far as we are concerned. Cheers!
