Although our instinct leadss us to impart reasons to things around us, usually that they're here for our benefit in some way, that doesn't necessarily mean that there really is a reason. We probably all have the same sense of awe and wonder, since we're part of the same species. I just don't project that onto a mythical supernatural being.
I don't think the world or the universe or time or space or life or us were created. Nor was there any purpose. And there might never have been such a thing as Nothing, although Stephen Hawking explains how particles/waves can spontaneously come into existence in his book The Grand Design, and Lawrence Krauss has also written a book called A Universe From Nothing.
The universe formed following expansion and opening up of some spatial dimensions; and research is seeking answers about how the universe was some billionths of a second after the "big bang", notably the Large Hadron Collider at CERN.
We might have to continue to have the humility to admit that we don't know everything for a very long time - perhaps forever; and I prefer this instead of invoking supernatural beings, which I don't consider plausible.
Now we understand so many more concepts of how nature works, such as space-time, expanding finite but unbounded universe, Big Bang, evolution, quantum mechanics, and so much more. But the Genesis attempt at explaining how the world came into being, and why people have to work to survive and suffer illness and death, was a step on the road to reaching today's knowledge. And today's knowledge will be a step on the way to future understanding for which we may not have concepts today.
The reason we're here living in the "Goldilocks Zone" ("Just right!"), talking about it is because this is one of the places and times in which we can exist. We were and are part of the universe, and we exist in it where and when we can. So our mental and instinctual mapping of reality, without special equipment and the benefit of theory and the higher mathematics employed by quantum physicists, would necessarily appear ordered; because we’re in the environment where we can be. If the environment were different, the probability is that we just wouldn't be here.
The universe is something around 13.7 billion years old, and is so immensely big on our scale that we can't imagine its size - and it's still expanding. It contains billions of galaxies, each containing billions of stars, at least some if not all of which have planets orbiting them. So if anything can happen, the chances are a virtual certainty that at some place at some time, it has happened. And we're here at this time, because this is where and when we can be. If you extend this Anthropic Principle to the hypothesis about the Multiverse, of which our universe is one of billions, that makes the chances even more of a certainty.
So there doesn't have to be a reason for things existing, nor is there any need for supernatural beings of any kind, let alone God. Space, matter, energy and forces behave the way they do on their own. And life and evolution are part of that, as is the experience of Self which is a construct of the brain and our senses.
Because we are part of the universe, our mental and instinctual mapping of reality, without special equipment and the benefit of theory and the higher mathematics employed by quantum physicists, would necessarily appear ordered; because we’re in the environment where we can be.
