Could be the aliens are rolled up in other dimensions, lack any use for morals, applaud our warlike tendencies. They might not be bipedal, possessed of opposable thumbs, or in need of spacecraft. Nothing says they're carbon based either. It could be we are the extraterrestrials, they are former earthlings, or that they're robots - though perhaps crafted by other aliens who may or may not be like the above. I'd say it wouldn't make sense for beings in a different environment to develop in an identical manner, but then what do I know about life on other planets - or wherever they live. If they live...

On a similiar planet it's logical to assume the evolution would be similiar. On a dis-similiar planet (i.e. gaseous) then it's hats off and who knows. But if they travel to our system and show interest, it is safe to say they have more in common with humans than insects.
