Religious people often threaten atheists with what will happen to them after death, if they don’t convert. Yeah, cause out of all the different made-up stories about what happens after death, it’s specifically yours that’s gonna be the right one. Right...
Let’s revert that question into “what if you’re wasting your life on religious bullshit”. It’s not as scary, because if it’s the case, you won’t notice you were wrong (that’s how being dead works). Still, your current life is the only one that you know for sure you’re gonna get. Are you really willing to waste it?
From a scientific point of view, of course I care for the god hypothesis. Its existence and nature are facts about our universe that are definitely worth knowing. But since we have absolutely no hard evidence supporting the existence of any god, anything we say about it and its nature must be either an uneducated guess, or just shamelessly made up.
From my personal perspective, however, should I care about god at all? Would it change anything in my life? Would I become a better person, if I just started believing against all reason?
