Reality is vast, vast beyond human comprehension.
The human brain may be vast, the human consciousness may be vast, but neither of them compares to the vastness of reality.
So no matter how much human consciousness grows, it will never be able to grasp all of reality.
It’s OK… it is just what is so.
Human consciousness, in its ambition, in its desire to comprehend reality, to reduce the risk that life is, to make life predictable and manageable, has been using models of reality: a model is a tool to simplify something complicated, and to make it comprehensible through generalization, imagination.
