What I Think About Aliens

[JrDude]

if you think about it, creatures have to adapt to their environment. If they lived on an amphibious planet that was dark most of the time, then they would look like that.

So if someone lived in the dark for 40 years, when they come out, they look green, have big heads, and have black eyes? And they'd be nude for some reason?
Yeah that makes sense.

it takes a long, long, LONG time for that kinda of change to happen

Yeah that makes sense.

if a species lived in the dark always, then they would have a white complexion, black eyes for good vision, and would be nude for some reason.

they may not have eyes at all

Does life exist elsewhere in the universe? Almost certainly yes, it'd be arrogant to say otherwise.

Does sentient life exist elsewhere in the universe? Probably, although the chances of our civilizations directly contacting each other are extremely low unless there exists a magical technology like Element Zero in Mass Effect that we haven't considered.

However, remnants of humanity will exist unto the death of the universe--we've sent satellites like Voyager into deep space, and even if those are lost, our radio signals will move relatively unhindered throughout space, as there really isn't anything to block or absorb them. For me, the fact that we've managed even that level of permanence on the universe is very comforting.

dunno if it was said earlier, but radio signals fade to static after about a lightyear.  Not that they wouldn't probably be recoverable.

I forget what the math was, but it came down to saying that the probability of sentient life existing outside of earth was something like 28000:1, considering the known size of the universe.
