The podcasts of Graham Hancock with Joe Rogan are very interesting. I'm very curious to what archeologists will find in the Amazon forest area in the coming years. Evidence is building up that there huge societies within the Amazon rain forest which where all destroyed by the European diseases brought there in the 16th century by Spanish explorers. Even more interesting are the conversations about the speculation that there might have been advanced societies 11000 years ago just before the last ice age started.
