ik a reson they would come here dimonds dimonds are the rarest things ever simply becuase they only form in supernoave explosions

Higher element above iron form in supernova. Diamonds form through intense temperature and pressure. the diamonds we would normally encounter would not have been formed this way. Though white dwarfs are thought to have cores of crystallized carbon. But this is not due to them exploding but them collapsing into a White Dwarf.

Lol this is my question. Why does everyone think that if we ever encounter intelligent life the first thing they'll do is try to kill us?

Predatory animals are the ones to develop more powerful brains. So it would stand that a species that develops a brain capable of interstellar travel would have evolved from a predator. It's also possible that predatory behavior didn't go away.

I suppose. Although, I would think any species that was able to not wipe itself out with those predatory behaviors and instincts by the time they were able to achieve interstellar travel would at the very least attempt communications of some sort upon encountering life.

does that mean that hyenas are getting smarter?
they used to be scavengers but are more and more often being a predator now.

They live in packs, right? Animals with increased social interactions usually are "smarter". Besides, there is no true scavenger-only animal as far as I know, at least not among mammals.

It's true that someone said once herbivores usually lead into evolutionary impasses. But can we apply the earthern eating behaviour qualifications on ecosystems we don't know?

If they were only interested in gathering resources why bother?

There is a degree of uncertainty, though we do see trends in each isolated system on the planet. This could give us at least a basic idea of what could happen else ware.

Essentially we get the general idea of what other unknown ecosystems might be. It may be like Earth. But then again it could be so odd it could spontaneously combust our minds. Anyway back on topic Aliens could be similar to animals here. We have no idea how other creatures on other planets could have developed.

Are you serious? That is completely false, Diamonds are formed by a pyramid of carbon atoms. (I believe it was carbon anyway)

Predatory animals are the ones to develop more powerful brains. So it would stand that a species that develops a brain capable of interstellar travel would have evolved from a predator. It's also possible that predatory behavior didn't go away.

But look at us. We don't have predatory instincts. (Of course there are cannibals...) Then Again we may just have a more advanced form of predatory behavior. We kill cows and pigs to eat them, Of course we eat fruits and vegetables as well but still.

mice? i couldn't find anything about their hunting behavior.

Even isolated systems stem from the same ancestor populations, though. But I guess we can make guesses at least :P

I hear many people saying alien life doesn't have to be based on the same principle, maybe some energetic beings and stuff like that. But when we're talking about life as we define it here on earth, then yes, there will be similarities indeed, The question is how many.

But look at us. We don't have predatory instincts. (Of course there are cannibals...) Then Again we may just have a more advanced form of predatory behavior. We kill cows and pigs to eat them, Of course we eat fruits and vegetables as well but still.

Our ancestors hunted for meat. Nuff said.

Sorry, by scavenger I meant carrion-eaters. No mammal eats exclusively carrion, they all hunt to some degree.

Bird =/= mammal

Look at the diversity of the ocean. I doubt we'll find stranger things on other planets. Example.
