I don't know if this find is going to pan out the way the initial talk about it is going, but I have to say the first wave of chatter about the remains of what may have been an ancient astronomical observatory being found in the Amazon has been interesting. I love finds that turn assumptions on their heads.
At the same time, my cynical side is flirting with the notion of taking bets on how long it'll be before someone hypothesizes the Druids either went to or came from Brazil. The second most likely claim will be that some of the Atlanteans escaped north while the rest went south, thus the parallel observatory situation. Before you claim none of us are that stupid, it's my understanding that Diana Paxson's deliberately fabricated names for Freyja's chariot-pulling cats in a novel Paxson wrote have since been taken for ancient lore.
And of course, if this first wave of hypothesis doesn't pan out, we'll hear far less about the debunking and still have to deal with the "Amazonian Druid" contingency. I suppose it won't be much worse than having to face the AD&D crowd.
