The interesting question is what happens next. If there are no gods, what does that mean for me?
There are probably as many answers to that question are they are people. But for the sake of argument, we can divide the response into two groups.
The first group say "There is no god. Yippee! That means I can do anything I want without fear of retribution."
The second group say "There is no god. Ooops. That means that we will need to reinvent some of that useful morality stuff that helps society to tick along quite nicely."
The first group might decide that self-interest is all that matters. The second group are tending towards humansim. And many many shades of grey/ gray in between.
