Recent LiDAR mapping of the southwestern Amazon Basin revealed thousands of geometric earthworks and roads belonging to the ancient Aquiry civilization, suggesting a dense population of up to three million people. Mainstream history has long insisted the deep rainforest could never support complex urban societies, preferring to view it as a pristine wilderness populated exclusively by small, nomadic tribes. This massive revelation confirms that thousands of years ago, the Amazon was heavily engineered and densely inhabited, reducing standard textbook timelines to speculative fiction.
