Giant Impact Hypothesis

The Giant Impact Hypothesis suggests that the Moon formed from a collision between early Earth and a Mars-sized body called Theia. When they struck, debris from both planets was ejected into space, creating a ring around Earth. Over time, this debris coalesced under gravity to form the Moon. This explains why the Moon's composition is similar to Earth's outer layers and provides insight into Earth's early history. It's a widely accepted explanation for the Moon's origin, supported by geological and astronomical evidence.
