"Yet there is nothing in nature that can't be explained by ordinary, everyday laws."

Horse dung.


String Theory, Quantum mechanics, Relativity, the origins of vision and hearing in animals are hardly ordinary or everyday the explanations for them are quite extraordinary and exceptional.

There are educated guesses about such things there is even some observation that supports the guesses, but they laws that govern many things in science are far from settled and ordinary.

It is a certainly that you can't have observed none of those things and therefor you take their existence on faith.
