There is a more direct relationship to other sources with the Psalms .
Just like your thread shows us an origin for the Noah story , many psalms can be compared with the original Egyptian .
Some psalms were said to be sung in Solomon's court or palace ( I am not sure if there was singing in the temple ? ) , it was part of the Egyptian rituals that these parts of the scripture seems to be drawn from ;
Harpist with percussion back up . The word appearing in Psalms - 'Selah' - is interesting to look up .

Papyrus rolls found in Tell el-Amarna revealed the full texts of more than a psalm of the Book of Psalms written in ancient hieroglyphs, and which preceded the Psalms of David written in Hebrew since more than 300 years. Together with historians from Berlin Museum, Egyptian Egyptologist, Selim Hassan, found three pages of Akhenaten's “The Great Hymn to the Aten” written to the sun-disk deity Aten, which were perfectly identical to those of the Books of the Torah, in spite of preceding the Psalms of David by more than seven centuries. They were inscribed on a right-side wall in Ay’s tomb at Tell el-Amarna, on 13 vertical columns at the entrance to the tomb.
