It seems if you’re just concocting a story from available evidence and theory, you come to Consciousness first, then Big Bang, then the flow of consciousness everywhere, enticing waves to become particles, and thence to hippopotamuses and so on. So it’s not turtles all the way down because turtles don’t appear until close to the hippopotamus era.
Before Consciousness, well, of course that’s the question that we so far seem to feel we can’t penetrate.
