Eden is a Sumerian word, translated as steppe. In other words, referring to the Garden of Eden is basically calling it the garden of the savanna wasteland. Mind, not that I believe in an historical garden of paradise, but the origin of the myth points to the wilds of Sumeria.

In this sense, the paradise lost was the drive of the individual from the wilds to the creation of society and civilisation. Origin of evil? I wonder what Hobbes would say about this.
