There’s no evidence for extraterrestrial life yet, but as our telescopes and probes scan outer space more and more, there are some hints that the conditions for life might not be as rare as we thought. For example, we’re finding compounds like amino acids, which are the building blocks of proteins, on comets.
One of the most exciting projects is NASA’s Kepler mission, which looks for planets orbiting other stars, and has been cataloguing thousands of them. Some of these planets are the right size, the right distance from the star, and made of the right stuff for life to be possible.
Given the size of the universe, I’d be surprised if there wasn’t life somewhere out there. It might be too far away to ever find or make contact with. Only time will tell!

Yes, I do!!! There is no way to be alone in the whole universe. There are soooo many stars that some of them should have live in them. Maybe not in the way we think about aliens, with this big heads and green skin. Maybe there are another organisms that don’t have DNA!! This is an amazing thought!

If you mean green people with bald heads and oval eyes, no. If you mean life on other planets, then yes. Recent work in physics suggests that, given enough time, life is highly probable.

Maybe, if by extraterrestrials, you mean life of any sort on another planet somewhere in the galaxy.
But, as a scientist, there is not even close to enough evidence to draw a conclusion, and really not even enough to formulate a good hypothesis.
But we keep looking, and using our best science to try to understand the information we have obtained.
But, I think we should spend more time and money trying to understand how to be good stewards of the resources we have on this planet than trying to find other life out there. -

Yes I do! I studied cosmology (the study of the universe) for some time. Based on the number of earth-like planets and the age of the universe, it is highly highly likely that life exists (or has existed at some point in time) on other planets.
