OMG, I have to write a 5 paragraph essay comparing the role of gods or god in the Epic of Gilgamesh...?

the Odyssey, Jospeh and His Brothers, Oedipus the King and the Song of Roland. 5 stories that each incorporate different beleifs and views. This is driving me crazy and I don't even know where to begin. I could compare 2 of these stories perhaps 3 but comparing 5 is kindof HARD to do. Any suggestions. I would really help if I could just get some wheels spinning in my head with some enlightenment.
