Chapter 1: Prologue- The Ways we Were
Our history is a big history in the sense that it began at the time of the big bang, or in other words day 0 of earth, and spans to today; a time frame currently considered to be around 13.7 billion years. To put it in perspective, the big bang is thought to of happened around 13.7 billion years ago, while the earliest life on earth was found to be around 4 billion years ago, first sign of oxygen around 1.3 billion years ago and dinosaurs around 329-164 million years ago. Geologists have been able to learn an immense amount of information from the earth just by looking at things such as the formation of rocks to the movement of the continents, things that no only happened 4 billion years ago, but are still happening today. From these studies we have been able to determine that for around 3 billion years the only ‘life’ on earth were the single celled prokarya that can still be found in many fossils today. Scientists were also able to determine that ‘natural disasters’ such as a mass...
