Did you ever think maybe god created this app as he loves everyone of us and wanted even non believers to find love?
Substitute "god" with magic. See how silly the question is? God=Magic. Magic makes everything possible and nothing provable. I like reality, with electrons lighting up this screen, processors determining 1's and 0's. 7 levels of the OSI model. All repeatable and demonstrable. No reason to add magic into a simple thing.
‘Even nonbelievers’?! Lol, the imaginary man in the sky is all generous and compassionate? Look around the world and at history: there’s zero evidence of any god, much less one who cares what goes on here.
Reality can be distressing, but us humans are on our own. Just my opinion, of course.
