I agree that some children who were raised godlessly in a godless world would invent imaginary friends as many children do until they are 6 years old, then they put those things away with their security blanket. Granted the mentally deficient children and the retarded kids might keep up their delusion into adulthood but normal people would have no religion that spontaneously generated in their brains.
As Joe Rogan points out, even the retarded kids would have issues with Noah's Ark.

I agree. But aren't our children already do magical thinking through video and on-line gaming (a lot of adults too). I think current religion is dying -- that's why there are so many splinter groups and more developing all the time. We are still gibbering ape like creatures, looking at the sky and believing what any authoritative person says.

that's impossible to answer

i think it depends on each individual as they grow up what are they looking out of life

I'm an agnostic and I raised my son without any religious beliefs and for quite some time, he referred to himself as an atheist and had a negative view of those who followed a religion. But he's almost 40 now, and has told me that he feels he lacked a sense of spirituality and community as a child and has now become somewhat spiritual and embraces an acceptance of religion in general, but not one specifically. I support whatever he chooses, but was kind of surprised at the outcome.

I have always been contrarian about the notion that children are "born atheist". Sure they are a blank slate and will have a strong tendency to adopt the beliefs and non-beliefs of their parents. But they have their own agency too, and they have their own brain which is bestowed by natural selection with the same tendencies to confirmation bias and agency inference as anyone else. And so, like anyone else, as they try to make sense of their environment and experiences, they will have the same exact tendencies to magical thinking as everyone else -- especially as children, who, before the age of about 10, have trouble distinguishing fantasy from reality as it is.

So unless they are actively taught critical thinking and skepticism by their parents they will tend to fall into the same errors as everyone else. The difference, if we could magically make religion and the memory thereof go away, is that they would not have a ready-made support system for religious faith and would be taught about reality instead of fantasy and so only a minority of them would develop elaborate notions of the supernatural.

But I've always said that humanity generally would reinvent religion in some form in that scenario just as they would develop tribalism and discrimination and wars and so forth ... these are all human things to do unless you are carefully taught to systematically work against these tendencies in yourself and others.

Sorry, disagree totally. Religion is filling knowledge gaps. Where did we come from, why are we here? What happens when we die? Why does it rain?
If children are raised with the answers to these questions, there would be no need to make up answers.
Science is just knowledge, all human societies had science. Maybe very primitive, but science non the less.
