Psalm 19:1-6

In his poem The mystery of things, where is it?, Portuguese poet Fernando Pessoa comes to this conclusion of what we see around us: “Whenever I look at things and think what men think about them, I laugh like a stream as it rushes over a stone. Because the only hidden meaning of things—Is that they have no hidden meaning at all.”

Is it true? Did the universe self-create? Is there nothing else?

Or was the Psalmist onto something?
