Meaningless as in to have no personal goal, nothing with an intent; completely without agenda.
A "personal" goal, in our human sense? An "agenda" that can be likened to the agendas that human beings might have? "An intent" as in a human or superhuman purpose that makes you feel your life is made meaningful by the ideology you project onto the nature of the universe?
And so, for you, must this anthropomorphized creator entity also have human emotions like anger, a desire for vengeance, jealousy, love and hate? And must this "who" you insist there must be, is "he" a male?
You don't seem to realize how many leaps of speculation that you pile, one upon the other, like a house of cards, each one having etched on it an assertion that assuages your doubt and curiosity - and the fact that you do not "know" any of the things you assert are actually real and true.
