Adding to what hanz0 said,

Probability that there is life somewhere out there: Pretty decent
Probability that there is life in our own galaxy : Not too strong.
Probability that we will ever come in contact or communicate with them : VERY, VERY, VERY, VERY UNLIKELY (unless we figure out how to teleport, time travel, etc.)

tl;dr: There may be life, but we will probably never communicate. Even if we get a message or something, or our telescopes are large enough to view a spacecraft, it is probably too late. What we see through telescopes are the past, the light takes billions of years to travel to earth. You might be looking at a star that died a billion years ago.

Yes I did kind of miss that point, but I also added that we weren't exactly separate from the "aliens" I think if there were other humans out there on different planets, then one of us must be directly related to the forming of the other human species on the other planet. But I do agree if left entirely seperate no planetary species would evolve exactly the same, and even if not seperate since the planets would have to be different so would the species.






... So far in our planets billions of years of existence and "God" knows how many asteroids have impacted this planet, and through our searches in space we have found I think 23 amino acids, which make up almost all life on this planet. That gives me reason to believe that these amino acids probably play a large part in the forming of life in other galaxies. I'm not saying fuck all about what's going elsewhere, I just think DNA being the dominant form of genetic encoding on Earth might not be a happy little accident. Of course everything we are and ever will be could just be a natural part of evolution, I don't know...But I'm sticking with we don't know shit.

Wow, just wow, closing this, I don't need this many idiots reminding me they exist this often.

For the record:
We are the only humans in this universe.
Other life forms from other places in the universe may not need DNA.
Other life forms will not have very similar DNA.
We are not the only intelligent life in this universe.
hanz0 says: I wouldn't necessarily argue that intelligent life is a given, but we can discuss that in a mildly more intelligent setting (i.e., not in Discussion).

Anyone who can't get over these basic facts needs to go read a fucking text book on biology and another on the big bang.
While we don't know everything we don't know nothing either, these are non-controvertible up and to the point that they have not yet been observed, but in every other way are inferred to be true. I am claiming no extra knowledge than what you can find by watching old PBS documentaries here ffs.

[EDIT] Having read the above post I think I actually need to elaborate (what the fuck?) on these basic facts:
We are the only humans in this universe, because to get humans you need our entire planets history of evolution. Evolution fits the environment, and it finds more than one way to do it.
Other life forms may not require DNA to live, because chemistry has lots of interesting molecules that can do biological jobs even as we know them now.
Other life forms will not have similar DNA because we DO NOT SHARE A COMMON ANCESTOR. "But Vox, meteors, amino acids, SPAACCEE!" No, fuck you and fuck your ignorance, AMINO ACIDS, ARE NOT LIFE FORMS, THEY ARE NOT A COMMON ANCESTOR.

I apologise for getting worked up, but I can only take so many shit-threads on; life on other planets and the butchering of evolution (seriously, discussion has plenty of them). I'd have closed this regardless of the idiots who posted here, this is like the third thread this month on this topic.
