	Age of the Earth - Wikipedia, the free encyclopedia
		This age represents a compromise between the oldest-known terrestrial minerals – small crystals of zircon from the Jack Hills of Western Australia – and astronomers' and planetologists' determinations of the age of the solar system based in part on radiometric age dating of meteorite material and lunar samples.
		Today's accepted age of the Earth of 4.55 billion years was determined by C.C. Patterson using Uranium-Lead dating on fragments of the Canyon Diablo meteorite and published in 1956.

	Age Of The Earth
		Scientists generally agree that the answer to the riddle of the age of the earth is carefully concealed within the earth's crust.
		Scientists assume the age of an index fossil by the stage of evolutionary history the fossil is assumed to be in.
		The popular age of 4.6 billion years old for the planet earth was derived by applying radiometric dating techniques to a meteorite called "allende" (a-yen-day), which scientists assume formed at the same time as the earth.

	Age of the Earth
		The most compelling argument for an age of the earth of 4.5 billion years are the large number of independent tests that have been used to confirm this date.
		Instead of trying to develop tests to actually determine the earth's age (whatever it may be), creationists are only interested in attempting to tear down the well founded results of scientists (after 50 years of geochronological research alone) that the earth is on the order of 4.5 billion years old.
		Scientists have no reason to claim an age of the earth of 4.5 billion years except for the results of decades of research and thousands of tests by independent researchers indicating the effectiveness of radiometric dating and that 4.5 billion years is the correct age of the earth.

	What is the age of the earth? How old is the earth?
		This age is primarily derived from two dating techniques: radiometric dating and the geologic timescale.
		Scientists who advocate the younger age of about 6,000 years insist that radiometric dating is flawed in that it is founded upon a series of faulty assumptions while the geologic timescale is flawed in that it employs circular reasoning [see our articles on radiometric dating and the geologic timescale].
		Those who hold to 6,000 years trust that the Bible is true, and that other factors explain the “apparent” age of the earth, such as the global flood, or God creating the universe in a state that “appears” to give it an very long age.

	THE AGE OF THE EARTH - 1 (Site not responding. Last check: 2007-10-09)
		It is theorized that the evolutionary age of the universe is 15 billion years, and the evolutionary age of the earth is 5 billion years.
		In Age of the Universe, we discuss a number of scientific facts indicating that the universe and our solar system are not very old.
		Based on the amount here, earth's age should be in the thousands, not millions of years.

	Geologic Time: Age of the Earth
		Nevertheless, scientists have been able to determine the probable age of the Solar System and to calculate an age for the Earth by assuming that the Earth and the rest of the solid bodies in the Solar System formed at the same time and are, therefore, of the same age.
		The ages of Earth and Moon rocks and of meteorites are measured by the decay of long-lived radioactive isotopes of elements that occur naturally in rocks and minerals and that decay with half lives of 700 million to more than 100 billion years to stable isotopes of other elements.
		The best age for the Earth comes not from dating individual rocks but by considering the Earth and meteorites as part of the same evolving system in which the isotopic composition of lead, specifically the ratio of lead-207 to lead-206 changes over time owing to the decay of radioactive uranium-235 and uranium-238, respectively.

	The Age of the Earth
		Most of the other measurements for the age of the Earth rest upon calculating an age for the solar system by dating objects which are expected to have formed with the planets but are not geologically active (and therefore cannot erase evidence of their formation), such as meteorites.
		In order to explain old isotopic ages on a young Earth by means of accelerated decay, an increase of six to ten orders of magnitude in rates of decay would be needed (depending on whether the acceleration was spread out over the entire pre-Flood period, or accomplished entirely during the Flood).

	Age of the Earth - EvoWiki (Site not responding. Last check: 2007-10-09)
		Today's accepted age of the earth of 4.55 billion years was first mentioned in 1953 by the geochemist C.C. Patterson at the conference Nuclear Processes in Geologic Settings.
		Houtermans had already published an age of 4.5 billion years in 1953 in a reviewed journal, but this age was also based on calculations from the same uranium-lead data on Canyon Diablo which were measured by Patterson and therefore not independent from the age determined by Patterson himself.
		The oldest minerals which are found on earth are zircons in Australia and show an uranium-lead age of up to about 4.4 billion years.

		Time and earth history is perhaps the most debated area in the whole question of the origin of life.
		The ratio of potassium to argon is considered in the calculations for the age factor of a particular rock.
		If the earth was billions of years old, the radioactive production of helium in the earth's crust should have added a large quantity of helium to its atmosphere.

	[No title]
		Ages calculated from these measurements increase with sample depth up to 22 million years for lavas deduced to be recent....it is possible to deduce that these lavas are very young, probably less than 200 years old.
		The connection between activity and age is made through a set of assumptions...one of the main assumptions of C14 dating is that the atmospheric radiocarbon level has held steady over the agerange to which the method applies.
		Age estimates on a given geological stratum by different radiometric methods are often quite different (sometimes by hundreds of millions of years).

	Some Miscellaneous Thoughts on the Age of the Earth
		This study gave rise to a broader subject of the age of the earth, for which at least some scientific evidence from both sides of the issue has been presented.
		I don't think it is a reference to an "age"; rather it seems to be a hypothetical reference to the earth being made green in one literal day.
		(Remember we are speaking of the age of the earth not the age of man.) Evolution falls (Biblically and scientifically) with or without a young earth.

		This radioisotope age dating book and DVD set by the RATE group is a compendium every creationist should have in their library.
		Even young earth creationists tend to assume the earth is possibly older than 6000 years due to radiocarbon dating.
		If the earth is billions of years old, then the rate of production and decay should have reached steady-state a long time ago.

	The Earth-2 Superman!
		Eventually, this world became home to all of DC's Golden Age versions of their superheroes: Superman, Batman, Wonder Woman, etc. Since these heroes had been operating since the 1930s and 1940s, they were now much older than their Silver Age ("Earth-1") counterparts.
		His powers and costume were based on the powers and costume that Superman had in the early 1940s, while his career as both Clark Kent and as Superman was extrapolated from what it was around the time of 1939.
		Like the Golden Age Superman, the Earth-2 Superman's powers are the result of his Kryptonian birth, his "flight" ability being limited to very long leaps.

	Evidence for the age of the Earth
		The "best" age for the Earth is based on the time required for the lead isotopes in four very old lead ores (galena) to have evolved from the composition of lead at the time the Solar System formed, as recorded in the Canyon Diablo iron meteorite.
		b) The age of the Galaxy is estimated to be 14-18 billion years from the rate of evolution of stars in globular clusters, which are thought to be the oldest stars in the Galaxy.
		The age of the elements in the Galaxy, based on the production ratios of osmium isotopes in supernovae and the change in that ratio over time due to radioactive decay, is 8.6-15.7 billion years.

		We can not look at current rates of rock formation, erosion, etc to determine the age of the earth because there may have been factors in the past that are not happening in the present.
		It is this: Though a few assorted dating methods give the age of the earth in millions of years, there are far more that limit the age of the earth to a mere few thousand years.
		However they should not be used to determine the age of the earth, as they have been known to produce more than one tree ring per year.

	Some thoughts on the age of the earth
		Many good-hearted Christians are convinced that a belief in an earth that is millions or billions of years old is not at all compatible with scripture, that the theory of evolution is full of holes, and that all scientists are atheists.
		Further, if the earth is only thousands of years old, then erosion and deposition, and other slow geologic processes, can't have been responsible for many of the geologic phenomena which we observe.
		The article left open the question of the age of the earth on which there is no unanimity among evangelicals and which was beyond the purview of this conference.

	GeoKansas--Geotopics--Age of the Earth
		Because all parts of the solar system are thought to have formed at the same time (based on the solar nebula theory), the Earth must be the same age as the moon and meteorites--that is, about 4.6 billion years old.
		Based on extensive sampling of the Earth's crust, scientists determined the present-day abundances of the four isotopes of lead relative to each other and to the parent isotopes that produced three of them.
		These calculations also yield an age of about 4.6 billion years for the Earth, which is consistent with the ages determined from meteorites and lunar rocks.

	THE AGE OF THE EARTH: PRINCIPLES
		Now think about this development: recently, I have read statements by advocates of a young earth claiming that they agree with that position in principle, but that they can use the scriptures, even allowing the diurnal and genealogical gaps, to set an upper bound on the age of the earth.
		I have also seen claims by some young-earth advocates that the earth is now “between 6,000 and 10,000 years old,” and that Jesus and His apostles took an analogous position on the age of the earth in the first century.
		The earth’s crust in places where these great depths of sediment is laid is sinking, under the weight of all that debris, at the same rate as the deposition.

		Slowing down down of the earths spin, giving 400 days in a year about 400 million years ago, which is what we observe from old coral growth rings, there are 400 growth rings a year instead of 365.
		The last comprehensive book on the subject was written in 1931, before nearly all of the evidence for Earth’s age had been collected, and the relevant evidence was scattered throughout a bunch of scientific papers that were difficult for the average person even to find, much less understand.
		For example, the age of the universe is currently thought to be 10-20 billion years-- a figure which fits nicely with the age of the Earth, but which was arrived at by different scientists, using completely different methods.

		Evolutionists claim that the Earth is billions of years old, while most Christians hold to the belief that it is only thousands of years old.
		In Genesis 47:8, Pharaoh asked Jacob his age, and Jacob responded 130 years in the next verse, marking 2006 B.C. as the year of his birth (Thompson, 1999a, 19:57-63).
		Whatever objections may be raised, Christians can be certain that the Earth is thousands of years old instead of billions.
