The first step is actually compelling mainstream archeologists to look at the evidence rather than dismissing it outright. There's a fine line between caution and willful ignorance, and its becoming increasingly clear that the latter has been holding up an argument that is increasingly becoming obsolete. That said, I understand the process is a long one and process is important.

If you subscribe to Graham Hancock's Facebook page you'll see a nice stream of mainstream news articles that he's been compiling as of late. Exciting times, like a domino effect. And since you're just becoming familiar, I would recommend reading Fingerprints of the Gods first to get an air of the controversy, and then his new book Magicians of the Gods. Lots and lots of references to look into, and very beautiful, compelling writing, too.
