Nothing exists outside of consciousness
No reason to assume I’m unique (probably has its own name, but like the cosmological principle)
Implies other things have consciousness and coexist in some fashion, which requires some kind of connection between them
Where did it come from?
Consciousness in humans is epiphenomena of brain activity, so probably spawns in when new life is created
Consciousness is a flow, not something that can exist in discrete moments (see how anesthesia skips time instead of passing it), implies to me that it cannot be bounded with a beginning or end other than the beginning of time
So consciousness would likely work as a branching flow, like a river watershed in reverse, or a tree that is growing. Each things consciousness is a branch off of whatever it came from and the trunk is God/the consciousness of the universe in its entirety.
