Even as an atheist, I think I've worked it out.
God likes gardening, forests, jungles, plains, mountains, glaciers, rivers, lakes, swamps, oceans, deserts so he makes millions of square miles of the stuff. It gets dull after a day or two, so he plonks two people in on particularly pleasant area, to keep him company.
However, he doesn't want it to turn into porn because he isn't able to get any nookie himself (nothing worse than watching other people getting their jollies if you're a virgin, yourself), so he doesn't even grant them the noggin to lust after one another.
We know what happened next and he/she/it has been punishing us, ever since, because we've got pleasures that they cannot experience for themselves, as an ethereal being and all. Envy, plain and simple. He can't operate an automatic rifle, so he uses natural disasters, instead.
