A synthesis of all that has been postulated and is known about the age of the Earth

This book spells out in detail how the age of the Earth has been determined over the centuries. First — the 'biblical' age: how was the date of Creation 4004 BC figured out? A date which is so important even today ... it is the basis of claims made by millions that the Earth is only about 6000 years old. Next — the response of geologists (and Darwin) for a very old Earth. Then, Kelvin's calculation of how long it would take for a hot Earth to cool down to its present state. And finally, today's answer ('billions'), based on the properties of radioactive materials. So, how old is Planet Earth?

Planet Earth and the other bodies of the Solar System are 4.5 billion years old. They reside in a galaxy (the Milky Way Galaxy) that is 12-14 billion years old, and are part of a universe that is 13-15 billion years old. In Ancient Earth, Ancient Skies, G. Brent Dalrymple, a geologist and widely recognized expert on the age of Earth, reviews the evidence that has led scientists to these conclusions and describes the methods by which this evidence has been gathered.

Davis A. Young and Ralph Stearley seek to convince readers of the vast antiquity of the Earth. They point out the flaws of young-Earth creationism and counter the impression by many scientists that all Christians are young-Earth creationists.

Negationism is an irrational but useful tool for manipulation. Almost nobody supports the Flat Earth model or the geocentrism, but some European educational laws still offer a confessional education that treats as real the myth about Adam and Eve. This book recounts the struggle that human mind has maintained, over two millennia, against creationist myths. The journey takes place between cosmogonies, theological dogmas, natural philosophy, Deism and the inevitable secularism of the Age of Enlightenment.
