Some think WE are aliens.....
I think there is simply at present ZERO basis for any stance regarding life of any kind anywhere but here on this individual little blue planet. We have NOTHING - absolutely nothing whatsoever - to indicate otherwise, but nothing - absolutely nothing whatsoever - to indicate that life is unique to here.
That doesn't leave much to discuss.....
Now, PURE THEORIZING (and doing so out of NOTHING - see above), it is often pointed out that the universe is big. And now we have reason to believe there are many times more planets than suns, which makes for a large number of planets. And most of those planets rotate around brown drafts - which may be stars more likely to have planets with life on them. But of course, all this is just pure numbers and pure guessing.
My OWN guessing out of absolutely nothing (and therefore having a value and significance of zero) is that life - OF SOME KIND - probably exists beyond the Earth. Quite possibly in our own solar system. But it may be extremely rare - maybe even nonexistent - for such life to be like us, or even to be both intelligent and technological and existing at this moment. And (getting back to that point of BIGNESS), it may well be we have no way of knowing about that life - even if it exists. There is no overnight mail delivery to galaxies say 10 billion light years away.... heck, not even to the nearest star (which is a brown drawf.... with planets.... although none seem likely to harbor life).
This is simple a subject where anyone can "swaffle" all they want, all day long - it all means nothing since we have ZERO information.
