Actually science can explain that. Turns out to mostly be about symmetry. Ask a large sampling of men and women to arrange a large sampling of faces from most handsome/beautiful to least and then take measurements of all the faces and the most symmetrical faces are beautiful and the least symmetrical faces are ugly.
So the point is that we are governed by things that science can explain. And you can ask all you want about big bang and atoms... Your attitude is very arrogant in the sense that your argument presumes we know everything there is to know... and anything we don't know must be because of some omnipotent omniscient being.
