Third-party evidence for Apollo Moon landings minus 6 million years. The test was done by a group of researchers headed by Alexander Nemchin at Curtin University of Technology in Bentley, Australia. The detection on Earth of reflections from laser ranging retro-reflectors (LRRRs, or mirrors used as targets for Earth-based tracking lasers) on Lunar Laser Ranging experiments left on the Moon is evidence of landings. Quoting from James Hansen's biography of Neil Armstrong, "": For those few misguided souls who still cling to the belief that the Moon landings never happened, examination of the results of five decades of LRRR experiments should evidence how delusional their rejection
Origin of the Moon that two bodies—each five times the size of Mars—collided, then re-collided, forming a large disc of debris that eventually formed Earth and the Moon. The paper was called “Forming a Moon with an Earth-like composition via a Giant Impact,” by R.M Canup. A 2012 study on the depletion of zinc isotopes on the Moon supported the giant-impact origin for Earth and the Moon. In 2013, a study was released that indicated that water in lunar magma is indistinguishable from carbonaceous chondrites and nearly the same as that of Earth in isotopic composition. The giant-impact hypothesis was again challenged in September
