The moon was spun out of the same stuff as the earth. That was fact in the early years of my education. A few years later there were multiple theories: co development, captured a wandering planetoid, the Thea impact, and a fourth one I can’t remember but I think it was something dumb like planetary mitosis. By the time I graduated the Thea impact was considered the only viable theory.
