An easy-to-read step-by-step explanation of natural evolution from the big bang to the rise of civilization.
Few people seem to be interested in questioning the existence of the universe. Most people are too busy dealing with the responsibilities and distractions of daily life. They do not have the time or the inclination to contemplate the existence of the universe. They just want simple answers that are presented to them in an interesting way.
Other people say that there is no point asking why the universe exists, because without any evidence, we can only ever guess the answer. But questioning the existence of the universe is essential, because until we understand our relationship with the universe, then how can we ever really know who we are or what we are supposed to be doing, other than to blindly follow our instincts and attempt to satisfy our desires?
Unfortunately, debate about the existence of the universe is still being clouded by popular religious myths that were devised at a time when we knew very little about the universe. While some people close their minds in blind acceptance of these myths, others close their minds in blind reaction against them.
There are countless ideas and opinions that have been expressed over the last three thousand years of written history. The most influential of these ideas will be discussed later in this book. But after stripping away all of the myths and misconceptions, and distilling the answers down to their purest essence, there remains only two possibilities.
