Are non carbon based life forms possible?

yes there  are living beings out there,there are billions and billions of planets out there in the universe.Are space program has only had to the power to explore a couple and make predictions about others. there are many planets out there that we haven't explore scientist say that every living thing needs water to survive.what about if there is some element out there that we haven't explored yet and it has the ability to support life out there. I don't know that if the live out there is more intelligent than us, but there is a chance that it might be true.
