Signs of its earthly origin have been found on the moon.

Scientists from the University of Washington have found that lunar rocks contain helium and neon - gases of terrestrial origin. And this proves that the Moon was once part of the Earth. Researchers suggest that the earth's satellite was formed as a result of the split of one large ancient planet. Probably, a large space object crashed into it, and it split into two parts, which later became the Earth and the Moon.
