I think it is impossible to understand Consciousness because Consciousness creates the brain and the whole universe.

If you think of Consciousness as the thing that is first and which creates all the rest, it answers a lot of hard questions - questions like why is it so hard to even define Consciousness?

Or weird paradoxes in QM.

Or things like: why do we all share the present moment?

Once you start to see Consciousness as the foundation of everything, it all makes a lot more sense. Everything fits together much more easily.

A lot of religions have also come to this conclusion.

There is a book called Biocentrism by Robert Lanza, which I thought was really good and went into details about this.
