17 Then I beheld all the work of God, that a man cannot find out the work that is done under the sun: because though a man may labor to seek [it] out, yet he shall not find [it]; yes further; though a wise [man] thinketh to know [it], yet shall he not be able to find [it].

then I saw all that God has done. No one can comprehend what goes on under the sun. Despite all their efforts to search it out, no one can discover its meaning. Even if the wise claim they know, they cannot really comprehend it.
