The giant impact theory is the one that is widely accepted by astronomers as having the most evidence to support it. This theory proposes that the Moon was created from debris that resulted from a collision between Earth and a Mars-sized object early in the solar system's history. The debris from this impact eventually accreted to form the Moon. The evidence for this theory includes the similarity in composition between the Moon and Earth's mantle, the Moon's lack of a significant iron core, and the tilt of the Moon's orbit relative to Earth's equator.
