What even is all of this? What are we and why do we experience any of this?
Consider the inner workings of a car. Most of the time, it just works. Sometimes it doesn't. But either way, it's just going without any consciousness or direct observer. Why aren't we like that, too, just going about our lives without anyone experiencing or observing any of it, like rocks falling down a slope on a barren planet? Or is there something or someone experiencing and/or observing things we assume nothing or noone is?
Did we come from nothingness? If so, why? If not, has this always been here? Maybe not the universe itself but whatever medium it exists in, if such a thing even makes sense. In the context of the big bang, what was the state of things leading up to it, why did it happen, where did it happen, did it create anything or was it just a rearrangement of something that was already there? Did the big bang even happen or are we misinterpreting various signs?
How much of reality do we see? How much can we see? Is what we know of and what we can interpolate from that a significant portion of reality or just a tiny sliver? Is it even finite or could any portion any being could know tiny compared to the full possibilities?
Is it even good to know the answers to these questions or is this whole thing just illusions created by more complete and eternal versions of ourselves to make an infinite existence bearable and knowing might just break the illusion until we reset and create it again?
