Ehh. Some things are just not as useful as other things. This follows directly from the laws of nature. All elements lighter than iron _release_ energy when they fuse together, while iron and anything heavier must _consume_ energy to fuse together. Carbon is one of the most important elements for life due to its unique chemical properties and immense number of useful molecular arrangements. The molecule we call water is essential to life as well, as it is incredibly effective, compared to the alternatives, at transporting materials to and from different parts of an organism (among other things [1]).
