Living on Arsenic

Not to brag or anything, but I called this years ago.
Since the basic concept of life and evolution is random chance, life should be able to be created from anything, given enough time. It may not have dna, or even breathe, but it could still be alive. And that's why I think it's so difficult to for us to find life on other planets. We're looking for earth life, organisms that breathe oxygen, are built out of carbon and 5 other elements, essentially follow a basic set of rules that we defined based on our own experience. It's like knowing what a fork is and trying to find a plate, glass, bowl, etc. They're the same thing, but you aren't going to find it by looking for a skinny, flat, slightly curved metal stick that splits to four smaller sticks. Life does not have to be anything like life on earth. The random chance that creates life essentially guarantees that. If we can find life on earth that violates a major part of our definition of what life on earth is, maybe we need to redefine life. </rant>
