A lot of religious wars would have been eliminated. Crusades, Spanish Inquisition, Holocaust, etc.

All the bad stuff people think will still exist, they just won't be able to hide behind their religion and use it as an excuse, So I would imagine these racists etc would be publicly ridiculed for their beliefs and shunned from society, however i'd like to think they'd be eductaed. There would also be less science denial and more investment in the sciences thus improving pollution reducing technologies.
Tribalism is slowly disappearing as people realise that all humans are human and the internet is helping educate people about world cultures and so there is less of the fear of the unknown that caused the differences between tribes. I don't feel that these negatives are "tendencies" but ill educated people making poor decisions made on their misunderstandings.

I think we'd all be better off if we approached problems using science rather than religion. Look at how conservatives are constantly trying to solve imaginary problems because of their flawed belief system. We spend so much time fighting over abortion and trans bathrooms and LGBT rights all because of ancient ideas about morality in ancient books. Religion creates a distraction which prevents humanity from focusing on our most pressing problems. If people come together and use rational arguments as opposed to religious ones, so much more can be accomplished.

I don't think that, by any measure, one could say that all of our problems would be solved without religion. That being said, so many wars are started because 'my invisible friend told me to kill you' , or because people are so concerned with their afterlife, they forget to live a good life here.

Getting rid of religion would be fantastic, but its not a solution to all our problems. There is still greed, avarice, bigotry, racism, and general hatred. And fixing those problems takes a lot more work.

I think some will always find a reason to harp on the differences between peoples. However, without religion a lot of that crap would end.

I think the human species has always sought a GOD However I do believe presently, the god will be substituted with the wireless aided mind. God is truly just a panacea for the cure to afraid.

It might be like someone on meth who by nature is a real asshole. Without the meth they would still be an asshole but less so. Either that or religion is a symptom of some deeper problem with humanity. Either way I say it's worth trying.

People would live to be nearly 200 yrs old.
Educational levels and SAT scores would skyrocket
Capitalism would give way to Cooperatives
War would effectively cease

We evolved competing for resources. I think conflicts would still exist, but we' d probably have more rational reasons for those conflicts.

It wouldn't matter. Human nature would still take hold. We already have tons of things we are divisive about without religion. The biggest reason why so many wars are fought in modern times is because of economics. Religion has nothing to do with why the nut in North Korea starves his people. Big business perpetuates pollution. Racism is probably as old as religion.

Can I just ask people on here about their definition of atheism.
Is Atheism the absence of belief in the existence of deities?
So Atheism is not a disbelief in gods or a denial of gods; it is a lack of belief in gods. (atheists,org)

Is that the general consensus here?

I guess actively denying the existence of anything requires proof..

religion is not a cause, but an aspect of society. Human's will be humans. Sometimes I wonder if Atheism isn't a reaction as opposed to a belief, in which case, I think of atheism as I do anarchy, the interim between new beliefs. An Atheistic world would be awaiting a new messiah. Now that would be fun.

Depends on why you assume there would be an atheist world. If we would have arrived at a point where all people would be atheist based on rational thought and insight, I think the world would be overall better. But if it would be a world were people are like they are now, all the religious bullshit would probably just be replaced by some other bullshit, only that this other bullshit would not be called religion. Would be something like flat earth, anti-vaxxing, chemtrails, homeopathy, racism, nationalism, belief in some odd ideology etc.

Oh, I've heard similar debates if we were all Christians nonsense.
If you think that all of us believing the same way you do would solve the problem of the world. There's a reason why there's a saying that goes "the road to hell is paved with good intentions."

I like to believe yes...but human nature is unpredictable...

I think conflict is part of human nature. We'd still have issues. Though the larger ones might just be different issues.

Good question.. My experience and observations around here have had me wondering the same thing… Are we wiser about everything because we’re wiser about one thing? And if we agree about one thing, would that transfer to everything?

I suspect the most important aspects of life would be in far (FAR) better hands, greatly outnumbered at least by those willing to consider a wider view. But when it came to specifics, it’d be like sibling rivalries are, petty squabbles in every direction…

No, an atheist world is not going to solve all our problems. As a species, we will still make enough mistakes to give us nightmares.

Are? Really dude,cmon....our. sorry.

Well some of those communist governments were non religious and they weren't exactly winners. Then again communism was their religion in a sense.

Watch this; Just before he died:

Dont you just love it... Your talking about MAN. A world with out religions ever happening? That's thousands of years they could of put the book down. No.... 1. They said they would mumble as they prayed. 2. They said they spoke in other tongues. What mystery!!! Let's try it and see what happens... And they took it and they ran with it and here it is... its a money maker!!!

I see no reason to believe that world would be much better or much worse compared to our world.

Spend a few minutes on the internet and you can find stuff just as awful as what you find on the pulpit. Just look at the alt-right and the redpillers. They found plenty of ways to be awful with no help from faith.

It's a start.
