As a fan of science fiction, I can assure you the series is not that! The format is to present established facts and exciting new archaeological discoveries, and then to speculate about some of the possibilities they suggest. So — “wildly speculative” perhaps. But to call the series science fiction somewhat demeans the hard work of the featured archaeologists. The article doesn’t mention this, but Season 2 features a team in the Amazon uncovering a series of never-before-seen geoglyphs using LIDAR. And there was nothing fictive about those geoglyphs.
