we aren't made of carbon directly though, we are made of amino acids that are made from carbon and a few other things (plus polysacharides and a bunch of fatty acids), so I wouldn't exactly say we are made of the same fundamental building blocks, as I expect there is way more than just our set of amino acids that will work (I would expect a number of different grouping of amino acids to work as separate groups and how the first proto amino acids happen to be put to use by chance to determine which grouping then goes on to evolve further and dominate because if you have to break something down and rebuild it as what you need it is way costlier than just dissasembling to aminos and reassembling so given enough time one should becomethe monopoly)
