Yes, I can answer this question in a 'scientific' way. It involves virtual particles --let's call them creatons-- interacting with matter in a morphogenetic field (earth) that gives rise to a genetic program that specifies reflex arches. Let's abbreviate it: creation.
It is a perfectly valid scientific hypothesis, even better than invoking space-aliens, since that only relocates the problem. Maybe it is even testable, and maybe I could even provide some biological indirect evidence for it. Do you like the idea? Best wishes Peter
