But you aren't starting with pennies, you are starting with all the atoms in the universe from which you need to get very specific combinations. Calculate the probability of getting DNA from that.
That's a strawman that has nothing to do with evolution. You should know by now that no reasonable calculation of probability can be made because the starting conditions are not known. In any case you are back to abiogenesis... not evolution.
These macro- vs. micro- threads are just getting silly. Anyone who has a clue about evolution and biology knows that there is only one mechanism and that micro-/macro- arguments are worthless strawman arguments constructed by people who have no idea what they are talking about.
I've never seen a river carve a valley out... so I don't believe in "macro-erosion". I only believe in observable changes like mudslides "micro-erosion". that's how silly the argument is.
