>>14050373biological organisms exist because they're good at existing. a certain arrangement of atoms sometimes turns out to be better at existing than another arrangement (miceles, rna, dna) and sometimes certain arrangements of those arrangements turn out to be better than other ones (rna that creates proteins that do things that help it exist for longer, dna that exists to help the fidelity of the rna last longer, micelles that protect them), and sometimes certain arrangements of those arrangements of those arrangements turn out to be better (bodies made up of cells that make different proteins that do different jobs to better protect the micelles that protect the dna that protects the rna)... ad infinitum.
you get the picture. There's no "magical life field" life is just the logical endpoint of the universe: existence that gets better at existing so it can keep on existing.
