Please excuse the presumption.
If I say there is an elephant in the room, this may be false, but it is understandable. Similarly, if I say someone created the universe, you may disagree, but it hardly seems unintelligible. Do you understand the word create? Do you understand the word universe?
Yes, it is what man must do to survive.
Do you understand the word universe?
Yes, it is all of physical existence, although I do not regard it as all of existence. (Life, consciousness, and volition exist. They exist "materially," that is, independently of any particular individual's consciousness or knowledge of them, inlike concepts, or other elements of concsciousness itself, such as emotions, which only exist if there is some one to have those concepts or conscious experiences.)
The only created things are those created by man. Everything else exists without contingency of any kind.
