finite number of ways in which CHNOPS comprising protein can be arranged, and most are junk, or non-selectable arrangements. For e.g. for a protein 92 AA long, with 10e122 possible AA combinatios, there is only 1 in every 10e63 functional sequence*. On the other hand, published extreme upper limit estimates puts the maximum number of mutations or CHNOPS re-arrangements at 10e43**. So, the total number of evolutionary CHNOPS re-arrangements is 20 orders of magnitude insufficient to find only one selectable state for evolution to preserve - a protein, let alone molecular machines, organs or organ systems.
Insufficient numbers, and empirically problematic to boot.
1) Not all proteins are equal 2) Whether something is functional, selectable, useful or beneficial depends on the entity it is functioning for. You are looking at specific protein for a highly evolved organism this is not comparable to a primitive life form that has no evolutionary history. What is functional for a bacterophage such as the lambda receptor, is likely useless for an early life form. And vice versa 3) You need to do more than use those numbers anyway - you need to establish how many functional proteins are clustered together in the context of the environment.
The problem you are trying to tackle is much more complex than merely comparing two numbers therefore your argument is insufficient to establish your conclusion.
