I don't understand what you're trying to point out. That groups of things can have behaviors that lone individuals don't exhibit? Yes, that is true, whether at the atomic level or the cellular level or the family level or the population level or the species level or the ecosystem level... it's very fascinating, to be sure, but in what way does that prove or disprove any sort of god? It's just the same Watchmaker argument, i.e. that complexity requires a maker, which it arguably does not. Complex behaviors, even flock behaviors, can evolve from the sum of its constituent parts. A pinball machine with eight balls in play will react very different from one with a single ball or no balls, but nobody accuses the pinball machine of being sentient (or if they did, I'd really like to play that machine).

Yes, and? I wouldn't worry about it too much... you'll likely die from something far more banal, like plain old climate-change-driven political instability, North Korea, the next anti-vax movement, etc.
