Search for Extraterrestrial Intelligence (SETI) Quotes

While NASA talks about 'Are we alone?' as a number one question, they are putting zero money into searching for intelligent life. There's a big disconnect there.

To me, it's the kind of interesting question the human race should be investing in. Is there intelligent life out there? Are there other beings out there?

The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us.

It's presumptuous for us to think we are the only beings in the cosmos.

I believe alien life is quite common in the universe, although intelligent life is less so. Some say it has yet to appear on planet Earth.

I've always thought that we, as human beings, would be naive and arrogant to pretend that we're the only life form in the galaxy.

The existence of life beyond Earth is an ancient human concern. Over the years, however, attempts to understand humanity's place in the cosmos through science often got hijacked by wishful thinking or fabricated tales.

People presume we've been somehow monitoring the entire sky at all frequencies, all the time, but we haven't yet been able to do any of those things. The fact is, all the SETI efforts to date have only closely examined a couple thousand nearby stars, and we're only just now learning which of those might have promising planets.

For many centuries, humans have speculated that there might be planetary systems around other stars and that there could be extraterrestrial life there and even intelligent being. However, those were simply speculations, and now we have evidence for the first part of these ideas.

I believe in aliens. I think it would be way too selfish of us as mankind to believe we are the only lifeforms in the universe.

If we knew we were not alone in the universe it would have a very, very deep impact on our worldview, on our understanding of our place in the universe.

Galactic plankton is undoubtedly out there, but it's statistically highly likely there's also another intelligent civilisation out there somewhere. Unfortunately, the distances and time differences are so great, communication might remain impossible.

Perhaps we've never been visited by aliens because they have looked upon Earth and decided there's no sign of intelligent life.

Astrobiology is the science of life in the universe. It's an attempt to scientifically deal with the question of whether or not we're alone in the universe, looking at the past of life, the present of life, and the future of life. It's an interdisciplinary study incorporating astronomy, biology, and the Earth sciences.

The universe is large and old, and the ingredients for life as we know it are everywhere, so there's no reason to think that Earth would be unique in that regard. Whether of not the life became intelligent is a different question, and we'll see if we find that.

It doesn't matter how much faith you have or don't have. I just don't buy the idea that we're alone. There's got to be some form of life out there.

Life outside of Earth is probably going to be really hard to find.

I think there must be some other life forms, even if they're microscopic.

Human beings have long wondered whether they are alone in the universe.

No company is hiring anyone to search for messages from aliens. Most people don't seem to think there's much benefit to it. The lack of interest is, I think, because most people don't realize what even a simple detection would really mean.

How can the human race be, like, the only living form in the universe? There have to be other life forms out there. I believe it.

Theoretically, there are planets with an environment that can support life. As yet there is no evidence that there indeed is life on other planets. It's only a matter of time before we get to know.

There was a time when the government cut off funding to SETI, basically, and I thought it was something that should continue, and it was a very interesting scientific question.

It's naive to think we're the only living beings in this universe.

We don't know why we are here and the context of our role in the universe, and the thought of an infinite universe. It's something the human mind can't really grasp. It's statistically impossible that there's not life on other planets.
