OK, OK, I take the hint!
Jeez. Just because I haven't posted an update in my build thread!
Seriously though.
although I believe it's true that in an infinite space, anything can and will happen, I don't believe we will see any non-terrestrial life.
Nearer the core of the galaxy, there is more solar radiation, it is more reasonable to suppose that life started there before anything here, and that therefore life there is already over [or so different to us, we wouldn't recognise it] due to the intense radiation.
Slightly further in than us, but still a long way out along the galactic disc, we may find more advanced civilisations, but there is still a major amount of luck required. If you take a point slightly smaller than our radius and then rotate that point around the galactic disc, the distance we'd have to search is almost immeasurable - at least with current technology.
Further out, civilisations, if any, would be younger. We could move outward and end up giving nukes to Neanderthals. That would increase our odds of being top of the civilisations in the Galaxy!
And we haven't met any aliens so far because we wouldn't recognise then if we had. The 'Grays' are a figment of our collective imaginations. Their short stature and spindly legs suggest a world with a lower 'gravity'. Unfortunately, although this would also require less muscle mass to hold up those huge heads, this would undoubtedly mean that every one of them would break their necks without some serious support here on Earth.
And speaking of heads, unless those eyes of theirs are compound eyes like an insects, there is no space left in them for brains as so much would be taken up with the eyes and mouth.
IF aliens do exist, the chances are that their race died out long before we arrived on the scene, or that we are so far away from them that we'll never find them, or that they'll come after humans have long left the stage, or that we'll never recognise them for what they are. either way, I don't see much to make a fuss about.
