What does Ecclesiastes 8:17 mean?

I realized that no one can figure out everything God does under the sun. No matter how hard people try, they can’t get to the bottom of it. Even the wisest people can’t fully understand it. Ecclesiastes 8:17 - Modern Text Bible

(No matter how much we study or think, we can’t fully grasp what God is doing in the world. Some things are just beyond us.)
