Information needs an appropriate and adequate source for it to amount to knowledge. A piece of paper has information. Knowledge is when a sufficiently sentient being accesses the paper with the appropriate tools (like knowledge of the language that is on the paper) and understands it.
Everything about us can be broken down to information. Right? We can label every aspect of us and we use language to communicate these things. It is always the case that knowable things ultimately amount to some kind of information. Do we agree on this crucial point? All types of information can be understood and deciphered fully if the appropriate and adequate senses/tools/recievers/receptable’s are in place. Agreed?
We amount to pile of information X, that goes through experiences (pile of information Y) and what that amounts to (Output pile of information Q) is either fully knowable, partially knowable or not at all knowable. If it’s not fully knowable, then it does not constitute and item of knowledge and so it is not required of that which is omniscient. If it’s something that is knowable (and it clearly is because we know what it’s like to be us) then the item of knowledge is known by that which is all-knowing.
Long story short, God can do all the things that we can do, but we can’t do all the things that it can’t do. Also, God knows all the things that we know, but we don’t know all the things that it knows.
Essentially, what I’m saying is this:
What X is like
What it’s like to be X like
What it’s like to be X
These are varying grades of intimately knowing the likeness of something. That which has the most tools/senses and the most experiences/informational content, is the one that can fully know all these varying grades of likeness.
