Measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4.6 billion years.

Segment from A Science Odyssey: "Origins."Geologists have calculated the age of Earth at 4.6 billion years.

Despite this, the momentum gained in the two decades prior to 1972 has made 4.5 b.y.

But it wasn't until the late 1700s -- when Scottish geologist James Hutton, who observed sediments building up on the landscape, set out to show that rocks were time clocks -- that serious scientific interest in geological age began."In a billion years [from now], it seems, intelligent life might be as different from humans as humans are from insects . To change from a human being to a cloud may seem a big order, but it's the kind of change you'd expect over billions of years." Freeman Dyson, Statement made in 1986, quoted in Asimov's Book of Science and Nature Quotations, p. [American mathematician.]"Slowness has really nothing to do with the question.An event is not any more intrinsically intelligible or unintelligible because of the pace at which it moves.For a man who does not believe in a miracle, a slow miracle would be just as incredible as a swift one."*G. Chesterton (1925)."The theory of evolution gives no answer to the important problem of the origin of life and presents only fallacious solutions to the problem of the nature of evolutive transformations . We are condemned to believe in evolution, but we will always search for a suggestion concerning the methods of transformations . Perhaps we are now in a worse position than in 1859 because we have searched for one century and we have the impression that the various hypotheses [of how evolution could have occurred] are now exhausted.Presently, nature appears to be more steady, more firm and more refractory [resistant] to changes than we thoughtbefore we had made a clear distinction between hereditary variability [within species] and acquired characteristics [DNA characteristics fixing each species]. Salet, Hasard et Certitude: Le Transformisme devant la Biologie Actuelle (1973), p. Several methods for dating ancient materials have been developed.This was dealt with in the chapter by that name (chapter 1).Second, generation of living organisms from non-living matter, or origin of life.From the mapped field relationships, it is a simple matter to work out a geological cross-section and the relative timing of the geologic events.His geological cross-section may look something like Figure 2.This is an important topic, for evolutionists want the history of earth to span long ages in the hopes that this will make the origin and evolution of life more likely.Yes, an understanding of dating methods is important, but we should keep in mind that whether or not these dating methods are accurate, really has no direct relation to whether evolution has ever occurred or could occur. Evolution can only occur by a sequence of, first, production of matter from nothing, or origin of matter.
