Dead on my friend.
Piri Reis will know doubt make an appearance in future posts as it's an amazing piece of evidence regarding the mapping of the planet in antiquity. Puma Punku is unique also as it looks to have been deliberately dismantled or destroyed prior to a flood caused by a cataclysm. The place is at 12,000ft elevation so it was a pretty 'biblical' flood.
The hypothesis of the builders doing a runner as they had prior knowledge of the coming destruction is an interesting one that I'll be looking into. Some cosmic event methinks.
Cheers for reading and a great comment as ever dude.
