Without organised religion, yes. But belief in God is still a religious belief.
Some people seem to think that they have rejected "religion" in favour of forming "a personal relationship" with God or with Jesus. And someone came up with "No religion, know God; know religion, no God", "Know God Know Life, No God No Life" and "No God, no peace; know God, know peace", which I suppose are somewhat catchy.
However, for me religion means beliefs relating to the supernatural, and any behaviour associated with those beliefs. So despite what they say, as far as I can see they also have a religion even though they deny it.
There are some sects or denominations that call themselves "Non-Denominational". But...if it makes them happy...
As regards the sub-question, although our instinct impels 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 hanging onto the kind of pride that won't admit we don't know it all and invokes 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.
