This is a complicated question for to know one might bc expected to
experience? However, we have the notion that more exists than we can
ever know. If the sum total of what exists is observed that is one
set of notions, but we have more out there than what is aware that it
exists. Thus, conscious existence is only a part of what exists. The
other parts do not know they exist. To experience even is only
partial, for experience is had without knowing. We experience the
world without knowing the world. We may come to know more and more
about the world, but we do not know the world completely, nor is it
likely we will ever know the world completely.
Knowing is akin to being smart. We will never be smart enough to know
everything. How smart is the smartest being in all the universes? Do
we make a mistake in assuming that being is smart enough to know
everything there is to know? For such a being to know all, it would
need to be from one end to the other of all that is knowable and it
would need to exist within a world that is by definition fully knowable.
When you assume such a being you assume that all exists in a way that
is knowable. All needs only to be not all for the supreme being to
not know all!
So what are you assuming? Is it that all is knowable?
