My current guess is that consciousness, over Eternity, wills itself into existence and that it already happened an Eternity ago. It's similar to the way mathematical sums are calculated over infinite iterations. Another way to look at is through Eternal Evolution where even the slightest superiority or "fitness" will necessarily have produced God, an Eternity ago, since Eternity can be divided into an infinite number of sub-Eternities. This is at least my mathematical analogy which I am able to produce on Medium infinite years into the future, fully conscious. There are a lot of cosmologists currently supporting an Eternal Cosmos theory so it's not entirely far fetched nor too far from Plato's Divided Line, conceived a mere nanosecond ago.
