|There were several [[Moon Theories|theories]] about the origin of the Moon. Most of the older theories had been discarded in the face of observations (for example based on lunar samples).<ref>Planetary Science Institute: [http://www.psi.edu/projects/moon/moon.html The Origin of the Moon]</ref> The currently accepted theory is that the Moon originated from a collision early in Earth's history which created an orbiting ring of debris from the iron-poor surface of the planet which eventually coalesced into the moon.<ref>http://www.astronomy.com/asy/default.aspx?c=a&id=2198</ref> This theory explains many things that spoke against the older theories, but other scientists have raised new points may speak against it if the theory fails to explain them.  

|There were accepted [[Moon Theories|theories]] about the origin of the Moon, but they were disproved by examination of lunar samples.<ref>Planetary Science Institute: [http://www.psi.edu/projects/moon/moon.html The Origin of the Moon]</ref> Since then there is no widely accepted theory among (non-creationist) scientists about the origin of the Moon.  One theory, which is untestable, is that the Moon originated from a collision early in Earth's history that created an orbiting ring of debris from the iron-poor surface of the planet, which eventually coalesced into the Moon.<ref>http://www.astronomy.com/asy/default.aspx?c=a&id=2198</ref> Many scientists have published articles against this hypothesis, noting (for example) that the Moon lacks many elements found in the Earth's crust.<ref>[[Moon theories]].</ref>
