Mass murders and genocide like Hotel Rwanda, WW2 with the Jews and many other places pretty much explain, there ain't no God. You were born and you fend for yourself base on your location and opportunities there. Daily praying ain't gonna change nothing, you have to get up and put the hard work in. The bible been revised by man so much a lot of it is not even true anymore. Also, a lot have open ended ending, meaning it needs a lot of explaining to do. So, yeah I don't blame why many people have ditch Christianity. I mean if certain keep failing on you at some point you gonna stop buying that brand, thing, etc.
