'Seems' in the Bible

So I loathed life because what happens on earth seems awful to me; for all the benefits of wisdom are futile -- like chasing the wind.

Then I saw all the work of God, and that man may not get knowledge of the work which is done under the sun; because, if a man gives hard work to the search he will not get knowledge, and even if the wise man seems to be coming to the end of his search, still he will be without knowledge.
