Hmmm but the fly must have some kind of incredible complexity compared to a pair of subatomic particles. I mean, it's made of an uncountable number of such particles, bound together in an extremely complex singular arrangement. And as i recall, the energy to separate 2 quarks (produce a quark anti-quark pair) is somewhere around the hundreds of MeV.

I wonder how hard you'd have to slap a table to spontaneously generate a fruit fly. Or the average number of attempts required.
