A titanic collision between Earth and a Mars-sized protoplanet formed the Moon? There is no universal consensus on this giant impact theory, because some details do not match. For example, the chemical composition of the two rocky bodies corresponds so closely as to suggest that the Moon was born from the Earth, not by a separate collision. However, the rapid spinning of the young Earth could throw out enough molten rock during the giant impact to form a chemically similar Luna. And there is a relationship between these events and the birth of life on Earth?
