Let's say that all religious people just left planet Earth and only atheists stayed here,what kind of progress would we see under science,politics,peace and economics.

Do you think that we will still need weapons if there was no religion?

yeh obviously, people will still be afraid of each other and need to defend themselves. Weapons would DEFINITELY still exist. Even when there's no religion there's racial hatred, even when people are the same color same religion same everything they create different teams, sides, tribes, sports teams whatever and always fight.
It might not even make much difference overall, science may progress faster, I think productivity would be raised due to less money being spent on bullshit, for example evangelists and other religious conmen.
There might be more progression in womens rights but then who knows, maybe the cultures where they use religion as an excuse to repress women might still be bastards to women and just use a different excuse this time. That goes for everything, maybe the people who are opposed to abortion would still oppose it without need for religion.

As long as resources are limited, we'll still have wars.

But if all religious people, believers, would disappear from Earth there would only be 1 billion people left. So we wouldn't have a resources problem for at least a couple centuries. More if we manage to avoid wasteful (world) wars.
Until we fuck it up again [pun intended].

However, since homo sapiens sapiens, us, has an innate desire to believe in miracles and superheros, a.k.a. bullshit, the society shaped by those remaining atheists and their offspring will soon invent other monikers for that inevitable societal addiction. 'Sports' anyone? As just one example.

Let them stay, I say. Because if they disappear their debts wouldn't. Which would mean that ours would be multiplied by 7. Because someone's got to pay. And we're the only ones left. I can't afford that. Can you?

Things would certainly be a lot quieter.

The average IQ in Mississippi might go up to triple digits.

In Congress too.

But would we have enough left to bitch about?

Fuck yeah. Too much poverty and nationalism as it stands.
