Check this out - The Fall of the Goddess (how Earth became Gaia)
This is from the site of a guy named John Lash... I stumbled across him last year and found his stuff to be really amazing and resonant...well, no wonder...
he translated the Nag Hammadi - which are the Gnostic Gospels... and I guess were too 'out there' to be included in the actual scriptures.
anyway, here's a link to the Gaia story (and yes, it is long and involved).
I think it is really awesome to help us see how she came into being the Earth FOR us and because she wanted to evolve WITH us.
It's the story of a goddess who fell in love with her creation...how awesome and beautiful... a celestial love story...

edit to add this excerpt:
"Sophia embodied is the living planet, all the way from its molten core out to the limits of the biosphere. Her passions have become the physical elements, solid, watery, aerial, fiery. In and through the elements Sophia experiences joy and anguish like every sentient being, and her emotional field encompasses the array of planetary sentience, entire. Having become a planetary body, Gaia, she does not forget what it is to be an Aeon, a dancing torrent of Organic Light, alive and aware, autopoetic, super-animating. She both the torrential stream of Organic Light and the material planetary body: she is is Gaia-Sophia.
But Gaia’s memory of her own divine condition is dependent upon what unfolds under the conditions of the terrestrial experiment. And in some mysterious way, the fallen goddess depends for self-recollection upon one species among all the other—that singularity, the human strain."
