The fission theory; The moons composition is similar to earths mantle and the fast spinning earth could have threw the moon from its outer layers. The capture theory; The Big gas planets like Jupiter and Saturn that have captured moons makes this theory possible. Lastly the co formation theory; Since the proto moon was close to proto earth the nebula material out of what they both formed from should be similar. These are all good reasonings behind these theories but the Giant Impact Theory Is the most accepted because nobody has have never been able to find evidence of any other planetary body on the moon before. But when the rock samples came back from the astronauts there was a sample of what was believed to be Theia which was formed by the impact theory on the moon and recent studies have proved that earth and the moon are made of different material. This supports this theory and makes it unique(Lunar Samples Support Giant Impact
