There hsa been something bugging me all day so I am just going to ask

[learning]

Non-believers do you have an answer as to how the world/universe was created. What about nature? Where did that come from? Who created us? I could go on but would love to hear your opinions

I think it is interesting to consider the way in which you frame the question. You (and the rest of us) have been heavily influenced by our culture (I was going to say "brainwashed" but that sounded a little strong) to view things from a particular standpoint. In my case (and in your case I suspect) that there is Someone In Charge i.e God. I suspect (though I haven't studied this, so I am speculating) that this is also to do with the way our brains were developed prehistorically i.e. we were successful at dealing with things in detail in our immediate area and bringing it under our control. We are not evolved to deal with the big questions - about long periods of time, about huge expanses of space. It literally blows our prehistoric minds - we are only adapted to deal with this valley or plain. And so we create a story to deal with it and so we become a story telling culture.

The "story" that I was told as a child was the one in the Christian bible. The Judaeo Christian standpoint underpins the way my brain works (and yours too). And that is why you pose the question you do. Which, in fact, makes no sense at all unless you are trying to make it into a story. Even the atheists/doubters are defined by the prevalent story - i.e. you believe in God, I don't believe in God. But who mentioned God? Why did someone have to have created us, or had an idea? It is a skewed, humanocentric (??) view of the world.

To me this sounds like the opening question that JW's ask.

I instinctively feel it's an odd question.

Big-bang, theory of evolution. These are both theories, and in time a better theory may come along, but scientists don't have any better ideas for now.

Fred Hoyle (a famous astronomer) denied the big-bang; his theory was that there was no beginning, but that view has been discredited now.

My parents created me .

There is another theory:
"I believe the world was created by a giant dog who licked everthing to shape out of custard, which he then microwaved with a special cling film over it to make it solid. ", and that has some support on MN

Non-believers do you have an answer as to how the world/universe was created.

You can assume a God, but all they buys you is "where did God come from".
Actually there is a deeper question, which is "where does 'where does X come from' com from". That syntactic mess asks where the "rule" that things must come from somewhere itself come from ?

What about nature?
I'm not sure what you mean by this. The set of things we see in the "natural world", are on the real time scale very short lived transitory phenomena.
Who created us?
We evolved, the evidence for this is enormously compelling. We can actually watch evolution these days.
But as for "us", to a significant extent, we created "us". A good % of the development of the brain was an arms race between humans. A lot of modern human behaviour cannot be explained by evolution, but can be modelled (to an extent) by looking at the interactions of humans. Humans do things that reduce their ability to survive and pass on their genes.

Some people have tried with a bit of success to model these behaviours as organisms themselves.
This has ideas as "memes". Religions look remarkably like viruses, both the computer and biological kind.
Some like Dawkins (Blind Watchmaker) see religions as a form of contagious mental illness, and you can use classical epidemological techniques to model it's spread and adaption to new populations.

Some like Steve Jones

have a softer view, that religion is fine for it's own area but gets quite silly once you get outside it's core competence.
