Moon Younger Than Previously Believed



"The stars did not yet revolve in the heavens; the Danaides had not yet appeared, nor the race of Deucalion; the Arcadians alone existed, those of whom it is said that they lived before the Moon, eating acorns upon the mountains." -- Apollonios Rhodios, librarian, Argonautica, ~246 B.C.

"These were Arcadians of Evander's following, the so‑called Pre-Lunar people." -- Plutarch, historian, Moralia: The Roman Questions #76, 1st century

"In the remotest times, before the Moon accompanied the Earth, according to the mythology of the Muysca or Mozca Indians, the inhabitants of the plain of Bogota lived like barbarians, naked, without any form of laws or religious worship." --Alexander Von Humboldt, naturalist, Researches, 1814

"The passages in Ovid as to the existence of the Arcadians before the Moon are universally known." -- Alexander Von Humboldt, naturalist, 1851

"We shall commence with a few of the principal passages from the ancients, which treat of the Proselenes. Stephanus of Byzantium (v. 'Apkas) mentions the logographs of Hippys of Rhegium, a contemporary of Darius and Xerxes, as the first who called the Arcadians proselenous. The scholiasts, ad Apollon. Rhod. IV 264 and ad Aristoph. Nub. 397, agree in saying, the remote antiquity of the Arcadians becomes most clear from the fact of their being called proselenoi. They appear to have been there before the Moon, as Eudoxus and Theodorus also say; the latter adds that it was shortly before the labours of Hercules that the Moon appeared. In the government of the Tegeates, Aristotle states that the barbarians who inhabited Arcadia were driven out by the later Arcadians before the Moon appeared, and therefore they were called proselenoi." -- Alexander Von Humboldt, naturalist, 1851

"...the pre-Hellenic Pelasgian inhabitants of Arcadia called themselves Proselenes, because they boasted that they came into the country before the Moon accompanied the Earth. Pre-Hellenic and pre-lunarian were synonymous." -- Alexander Von Humboldt, naturalist, 1851

"Capture of our Moon becomes the only option, it cannot have been created from the Earth." -- Wallace Thornhill, physicist, October 2000

"Currently, the moon is moving away from the Earth at such a great rate, that if you extrapolate back in time — the moon would have been so close to the Earth 1.4 billion years ago that it would have been torn apart by tidal forces (Slichter, 1963)." — Dennis J. McCarthy, biogeographer/geologist, 2003

Science Daily: Moon Younger Than Previously Thought, Analysis of Lunar Rock Reveals.

The research team, which includes scientists from the Natural History Museum of Denmark, Lawrence Livermore National Laboratory, Carnegie Institute's Department of Terrestrial Magnetism and Université Blaise Pascal, used newly-refined techniques to determine the age of the sample of a FAN that was returned by the Apollo 16 mission and has been stored at the lunar rock collection at the NASA Johnson Space Center.

The team analysed the isotopes of the elements lead and neodymium to place the age of a sample of a FAN at 4.36 billion years. This figure is significantly younger than earlier estimates of the Moon's age that range to nearly as old as the age of the solar system itself at 4.567 billion years. The new, younger age obtained for the oldest lunar crust is similar to ages obtained for the oldest terrestrial minerals -- zircons from Western Australia -- suggesting that the oldest crust on both Earth and the Moon formed at approximately the same time.

This study is the first in which a single sample of FAN yielded consistent ages from multiple isotope dating techniques. This result strongly suggests that these ages pinpoint the time at which this sample crystallised. The extraordinarily young age of this lunar sample either means that the Moon solidified significantly later than previous estimates -- and therefore the moon itself is much younger than previously believed -- or that this sample does not represent a crystallisation product of the original magma ocean. Either scenario requires major revision to previous models for the formation of the Moon.

...suggesting that the oldest crust on both Earth and the Moon formed at approximately the same time.

Meshing just fine with the giant impact hypothesis of the moon's origin.

The idea that there were people around prior to the moon's arrival is utter bullshit.

History is bullshit because science is infallible?
