What's the point? If you think the world is bad now, then I doubt you would like a world where humanity has yet to learn from past mistakes. All the race, sex and gender inequalities will more than likely repeat themselves in almost the same way, any beneficial things humanity has progressed such as medicine will be starting from scratch again resulting in pretty much the same amount of death and suffering, wars will still happen because bad people exist, people will still get put in positions of power that other people don't like...Dumb stuff like 'drowning witches' because there was a time we were stupid enough to believe that crap...Pretty pointless to repeat all that, because that's all that would happen. Maybe not in exactly the same way, but it would happen, and it would be just as bad the second time around.
Currency and religion would come to exist anyway.
I don't believe in religion, but I believe that it's almost a natural thing for humans to create, at least if factual information isn't there to provide any answers (which it still isn't now, and definitely isn't in a 'reset' world). "Man in sky make world" was at one time a ground breaking theory...
Currency as well. Might not be dollars or pounds, but we would create some sort of currency eventually. Even if we did imagine currency didn't exist, we would still pretty much have to resort to trading things we have for things we want/need, which is kinda where the idea of currency started in the first place.
