The ultimate self-containment paradox: The universe, by definition, is the totality of all that exists. Therefore, any explanation for why the universe exists, or how it came to be, must posit something (a law, a cause, a god) that is itself part of or prior to that totality. This leads to either an infinite regress (what caused the cause?), a logical circle (the universe created the conditions for its own creation), or an arbitrary stopping point ("It just is"). The universe cannot explain itself from within; it is the ultimate brute fact, and that unsatisfying brute-fact-ness is the hard problem.
Example: Asking "What caused the Big Bang?" might lead to "A quantum fluctuation in a prior vacuum state." But then, what caused that vacuum state and its laws? If you say "A multiverse," what explains the multiverse's rules? The hard problem: Every explanation smuggles in new, unexplained elements. The universe is like a book that tries to tell the story of its own printing and binding. The final page would have to be outside the book, which is impossible if the book contains all pages. Hard Problem of the Universe.
