sorry, I meant that we do not all share the same proteines, as we all do the amino acid bricks. But sure, we all share the same bricks, but that does not make us related, just as painting of Leonardo does not relate to a bird dropping on a canvas. Both may be made of the same materials, but they are certainly not related but of mutualy alien origins.

Again, does the wheel common in many devices mean that the bottle shares a common origin with the car? The car has wheels because it cannot function without them. The bottle is round because the tool that made it was round too, the blow pipe itself, that is. It's not because 2 objects share a mathematical concept or basic building blocks that they have necessary the same physical or design origin. Some things happen to be shaped thus because by pure chance the tools manipulating them gave them their shape naturaly, other things share a shape because by design they had to be shaped that way. Even beetles push wheels and balls of clay.

There are 20 odd common amino acids.
The DNA/RNA backbone Is built of just four; Thymine, Adenine, Cytosine and Guanine. The DNA/RNA backbone could have been built of any 4, or any 6 or 8.
If there were multiple beginnings we would certainly see some beginning that used a different group of amino acids.
