Sea Breeze though you are dismissing Ecclesiastes as "is part of the "WIS[D]OM LITERATURE" in the OT" and "is written from a carnal point of view, same as an atheist" the book actually doesn't teach atheism (as much as I might wish it did). For, example verses 7 and 9 from the same chapter 9 state belief in God. That chapter is actually expressing a Jewish religious view in Judah that there is no afterlife at all. Perhaps it was the same view as the Sadducees whom as you know denied the resurrection of the dead and the existence of spirits and angels. As you know, the Sadducees ran the Jewish temple of YHWH/Yahweh/Jehovah in the second temple period and worshipped Yahweh, offering sacrifices to Yahweh. A scholarly book I quoted from months ago says that at a certain time in the history of biblical Judaism there were religious teachers and worshipers of Yahweh who taught the people that there was no afterlife at all. The book says those teachers were trying to refute the idea of other religious Jews. peacefulpete is correct in saying that there was a diversity of Jewish religious views about an afterlife, but his post on page two of this topic thread left out the view that some Jewish worshipers of Yahweh believed there was no afterlife at all.
The book of Proverbs is also wisdom literature, yet it also states beliefs in God, it even says that wisdom comes from God. As a result, just because a book in the Bible in the Bible is wisdom literature, that mean it is atheistic. Atheistic books didn't make it in the Hebrew Scriptures, scriptures which the NT says are inspired of God.
Fisherman, though many Christians teach that the book of Ecclesiastes was written by Solomon, a number of modern critical scholars say it was not written by him, despite the extant copies of the book saying it was written by him.
