Natural selection has made some very damn weird looking things, here on Earth. If our DNA was off just by a few percent, we would be ducks. Imagine what would be the difference with something that has 95% difference, or has no DNA at all.
And mutations that occur in nature, on which evolution is based on, are random. So the fact that we look the way we do is pretty much a direct result of randomness. It's not like we're this perfect schematics plan nature everywhere strives for.
So to better answer the previous question, yes there is a possibility that they may be humanoid. But there is also a possibility that there is an extraterrestrial race of Joe the Truckers, feeding off of each other's head lice. It's just not very probable.
Mutations in nature are random, but typically only the mutations that contribute to the survival of the species will survive. In the long run, it is based heavily on the environment and the survival capabilities of the species with specific traits. It's not the species that is random, it's the environment being random that causes randomness in the species.
And something that has no DNA would likely use RNA instead, so chances are it would be a form of virus, which is a form of life, but not one which we commonly associate the term of "living" to.
- The Fantasy:
- I don't like humans because we're destructive by nature. I really dislike that about our species.
As for aliens having two arms and legs, maybe, maybe not.
I watched Into the Universe with Stephen Hawking on Discovery Channel tonight. In the episode about aliens, he says it's likely aliens would have some sort of legs, especially if their planet resembles our own at all. Legs come in handy for walking on ground.
Well when we do find aliens, they may be as destructive as us, or less, or more. Who knows.

- ^Wheels might be better...
Yes... let us find a species that evolved from the common automobile... xD
