I can see this is another one of those "infinite" threads.. like is there a god?..
But anyways,i'll give my 2 cents..
To say we are the most civilized or most advanced beings in the universe would be like saying that the world is gonna kick the bucket(end) tomorrow.
So,I say it's pointless to even mention that as we have no idea what's out there in deep deep space.(lmao,i had to use 'deep' twice just to reiterate the continuity of space).
I mean,for all we know,there "could" be a more uber advanced race with technology so powerful it would make our Atom bombs look like an ants' fart.
For me,if i see it,i'll believe it.
