There are similar accounts in that book and it all seemed not-so-extraordinary until I got to the accounts of maps that described features of Antarctica. Whether it's true or a hoax, the human mind is amazing. The book contains accounts of evidence of tides of human civilization: planned cities in Pakistan, well-developed waste management systems, advanced ship building and navigation (for the time they lived), possible advances in weapons and warfare, including nuclear weapons (evidence in an Indian desert and writings describing a nuclear explosion), writings describing space travel and some other marvels of the ancient world.
