I think that has to be a definite yes. But I think the real question is, are aliens close enough for us to discover them? Space is unbelievably big. In the last few decades, we've learned almost every star in the cosmos has planets. Our galaxy, the Milky Way, is estimated to have up to 400 billion stars. If each of those has five planets, we'd have...
Yes, but that's a bold assertion. So, let's be clear what we are talking about. I consider the term "alien" to reference all manner of life, as we understand it on Earth, resident in places other than on Earth. Having said that, there is currently no detailed consensus on the definition of "life". It is a very complex concept. But if we found somet...
I'm of the opinion that it's only a matter of time before we find something that resembles biology somewhere other than on Earth. This is because we're increasingly finding various potential pockets in our solar system that may be hospitable to life as we know it. For instance, consider the under-ice oceans of Europa and Ganymede (two of Jupiter's ...
Yes, but they probably don't look like us. There are more than 100 billion planets estimated to exist in our galaxy alone (with some six billion potentially being Earth-like). Therefore, the probability that life exists elsewhere is all but confirmed. When we hear the word "alien", however, an image of a humanoid lifeform usually springs to mind. B...

If we use purely empirical data and assume the question refers to any type of life outside of Earth that is not related to human activity, then the answer – as far as we know – must be no. But, of course, our knowledge relating to this question is finite; we have not investigated every corner of the Universe ...
