Apparently every animal form on earth shares at least some DNA with humans. This brings me the question: If there is other life elsewhere would it necessarily share at least some DNA with us? Is it possible to be an animal form and not have it? If not, would we define it as life?

Good question. It would imply some sort of common ancestor.

That would assume that life on earth came from somewhere else or that some how, life on earth escaped and landed on another terrestrial planet.

Since Pioneer 10 only left our solar system in 1983 I would postulate that the later is impossible. That leave someone else dropping off organic matter on earth a few billion years ago. I guess that is possible as well but who knows. There is circumstantial evidence (Nazca Lines) that something not of this earth may have been here but the Nazca Lines are only about 2,500 yrs old at most so is well after life originated on earth. Stonehenge goes back to 3000 BCE and again, well short of the origin of life.

I guess the other possibility is that the molecules that lined up to make us are just common in the universe and if the same/similar environment exists elsewhere, that same type of life will propagate there as well.
