If you do not believe in a deity, you would have to believe that everything came into existence without the need for conscious intent.
That sounds suspiciously like a false dichotomy, to me.
That is a belief system.
Arguably; it could, rather, be seen as a conclusion from the available evidence and therefore a provisional realisation without any need for a faith position at all.
The profound opening of John's gospel, (in the beginning was the word), implies that conscious intent was there from the start.
"The Wheel of Time turns, and Ages come and pass, leaving memories that become legend. Legend fades to myth, and even myth is long forgotten when the Age that gave it birth comes again. In one Age, called the Third Age by some, an Age yet to come, an Age long past, a wind rose in the Mountains of Mist. The wind was not the beginning. There are neither beginnings nor endings to the turning of the Wheel of Time. But it was
a beginning."
See, that expressly says that there was no start, and it's a much, much better book than yours (although the TV series of both were terrible).
