Source? Evidence that your one specific combination is the ONLY life-sustaining cominination? Evidence that insists that life must have jumped from zero to fully-formed cell--with no intervening reactions--in a single step?
The liklihood of those some 2,000 enzymes occurring at the same place in that pond as necessary to create one (1) protein cell is 1 to the 40th power. That is, 1 X 10 followed by 39,999 zeros.
Based on what assumptions? How big is your pond? Of what is it comprised? Why assume that each molecule exists as an individual entity? What energy source(s) drives the reactions? Do these reaction occur at the surface or throughout the entire volume? What about thermal vents? Are there any other ponds that we might consider? Are they on this planet or on ANY planet? Do you have probabilities for the other planets? Do you see where I'm going with this?
A word of friendly grammar advice: try, "of what is it composed," or, "what does it comprise". The parts compose the whole, the whole comprises the parts. (Yeah, I know, grammar/spelling corrections are bad netiquette, but I see this too often.)
All good questions, none of which are answered by Darwin's flawed Theory. Thank you for underlining some of the flaws in his Theory.
Oh, and in reply to your straw-grasping query: "Do you have probabilities for the other planets?"
Note that the statistics I quoted include the estimated number of atoms in the entire universe... which included all planets the last time I checked.
