Sorry if I'm digging up something that's been discussed, but I want to comment on the following. God is great because God created everything, but I can't help but feel that Thomas Edison and Tesla earns more of my respect. If God is perfect then it would be trivial for him to create anything imaginable. Whereas people like Tesla, Edison, etc were mere humans who have limited tools and intelligence and they are able to come up with something incredible. As an analogy, an 80 year old woman running a mile is much more impressive and worthy of praise than if it were 30 year old healthy man, because for the young man it is expected given his abilities. In the same vein, God created and placed disbelievers here and then tell them to believe. Yet for a lot of non-believers, God never created a situation to undeniably show them his presence, unlike many in church who have seen it.
