Quarks? WHAT ARE THEY MADE UP OF?

I'm questioning the confidence modern physics puts on the theory of big bang. Suppose that there was this quantum event that caused a big bang, how does that idea support that there was "nothing" before the big bang? To me the BB theory sounds like creationism given a scientific context. If you can say the big bang was the first event in the list of events that is our universe, then that makes no sense because how can something be acausal only once? The laws of physics then should also be acausal since, because if it happened once, why not at other times?

The second alternative, eternal inflation is just as mysterious. How can something be eternal if all evidence points towards a universe going into heat death? Another problem with eternal theories of universes is that, consciousness would be duplicated at infinite universes. So how is it that we are not teleported in our sleep to different universes and experience consciousnesses of other "bodies" in other universes, when the only factor required for consciousness is a particular brainstate which is ubiquitous throughout the multiverse?

The third alternative: which makes the most sense is the universe was created literally 1 nanosecond ago. Think about this: you don't live in the present, you are living in the past. Your body takes a few nanosecs to process a thought and make it conscious, and by that time, the wavefunction of your body has already evolved, therefore what you are observing is the past and not the true present. Hence if the universe is truly in a superposition at all times, with nothing that can cause a spontaneous collapse, then it makes most sense to talk about a universe that doesn't exist in the past or in the future. Just the appearance of coherent memories to give us an illusion of a definite causal past/present/future.
