We have already found alien species.
Right here on this very same planet:
Dinosaurs.
We would have never even known about their existence if we had not chanced upon their remains.
So it's not just the vast distances of space that separates species from each other, it's also incomprehensible stretches of time.
Just from the amount of variables involved and their ranges (the number of planets, the extreme environments in which we have already observed life), it's obvious that we are not alone.
BUT we may never meet anyone.
Just like how there's billions of people on Earth but millions die alone, to use a topical metaphor given Valentine's Day. :)

- Razengan 7y agoThose are really interesting! The point was that even if we could physically visit planets or reach them with communications, we would have to do it in the right time bracket. Any life (of interest) on them may have long since passed on, or not capable of interaction yet. Mars may have once had life, and we may never know of it.
- Mike345845 7y agoNo, Dinosaurs are not extra-terrestrial aliens, which is what SETI is looking for. And they are not "true" aliens (what's the correct term for this?) Dinosaurs and Humans share a common ancestor. We evolved from the same origin. We both have DNA. We are literally cousins. SETI is searching for life that originated from dead matter independently from earthlings. Those extra terrestrial beings may not necessarily have the same basic structure (DNA) as us.
