Hypothetical situation here, but what if someone proved, beyond any shadow of a doubt?

Question

that god didnt exist? what do you think would happen to the world? for the sake of this question, there is absolutly no way that it can be disputed, someone proved that, beyond any shadow of a doubt, god didnt exist....now what? would there be more chaos? or would people be peaceful because of less religious intolerance? what would the world come to if someone proved that absolutly, 100% god did NOT exist?
