The Instant New York Times Bestseller
Was an advanced civilization lost to history in the global cataclysm that ended the last Ice Age? Graham Hancock, the internationally bestselling author, has made it his life's work to find out--and in America Before, he draws on the latest archaeological and DNA evidence to bring his quest to a stunning conclusion. We've been taught that North and South America were empty of humans until around 13,000 years ago - amongst the last great landmasses on earth to have been settled by our ancestors. But new discoveries have radically reshaped this long-established picture and we know now that the Americas were first peopled more than 130,000 years ago - many tens of thousands of years before human settlements became established elsewhere. Hancock's research takes us on a series of journeys and encounters with the scientists responsible for the recent extraordinary breakthroughs. In the process, from the Mississippi Valley to the Amazon rainforest, he reveals that ancient New World cultures share a legacy of advanced scientific knowledge and sophisticated spiritual beliefs with supposedly unconnected Old World cultures. Have archaeologists focused for too long only on the Old World in their search for the origins of civilization while failing to consider the revolutionary possibility that those origins might in fact be found in the New World? America Before: The Key to Earth's Lost Civilization is the culmination of everything that millions of readers have loved in Hancock's body of work over the past decades, namely a mind-dilating exploration of the mysteries of the past, amazing archaeological discoveries and profound implications for how we lead our lives today.Binding Type: Paperback

Don't buy, check HIS github or google collab for EVERYTHING that's in this book. NO SOLUTION
Format: Paperback
I never write reviews, but after this book I need to. DON'T BUY IT. DO NOT BUY THIS BOOK. Feels like a money grab. You are literally paying money for NOTHING buying this book. Long story short: GO TO HIS GITHUB AND GET IT ALL FOR FREE BECAUSE HE DOES NOT PROVIDE SOLUTIONS. GO ON GITHUB OR GOOGLE COLLAB AND CALL IT A DAY.
In the intro he makes it seem like you don't need to know much programming or any tbh. He says if you have never programmed you should be able to read this book. HELL NO, I mean yeah you could probably figure it out, but I would not let someone that doesn't know any programming to start with this. I'd probably tell you to learn the basics of python for a week before starting at the very least.
He also makes it seem like you don't need much knowledge of physics. Meh, maybe.
Anyway the main reason not to buy: IT'S ALL AVAILABLE FOR FREE ON GITHUB THAT HE PUBLISHES FOR FREEEEEE. You can also use google collab, which he has up for FREEE. and if you are are a beginner I'd recommend you go off teh google collab, that way you don't have to deal with downloading anaconda and setting up an enviroment in jupyter which I think can be intimidating for a beginner. And this book doesn't really give much help in setting up everything in jupyter notebook.
Also another point. He'll lead you through an example each lesson, but for the exercises he has you working on he doesn't provide a solution ANYWHERE. like why tf would you buy this book? How do you expect to learn with no feedback? You need to search online for ways to solve these problems, which I think is not a bad skill to have, but if you are new to a subject or trying to learn and you pay for a book why can't i at the very least get some solutions. even math textbook give you solutions, because the understanding is that you can make your own attempt and CHECK TO SEE IF YOU ARE RIGHT. DUHH !
