Five serious theories have been proposed for the formation of the Moon (not counting the one involving green cheese):
1. The Fission Theory: The Moon was once part of the Earth and somehow separated from the Earth early in the history of the Solar System. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came.
2. The Capture Theory: The Moon was formed somewhere else, and was later captured by the gravitational field of the Earth.
3. The Condensation Theory: The Moon and the Earth condensed together from the original nebula that formed the Solar System.
4. The Colliding Planetesimals Theory: The interaction of earth-orbiting and Sun-orbiting planetesimals (very large chunks of rocks like asteroids) early in the history of the Solar System led to their breakup. The Moon condensed from this debris.
5. The Ejected Ring Theory: A planetesimal the size of Mars struck the earth, ejecting large volumes of matter. A disk of orbiting material was formed, and this matter eventually condensed to form the Moon in orbit around the Earth.
There are three main theories of how the moon came into existence. The theories are as follows: the moon was captured by Earth's gravitational pull, the moon was originally part of the earth's crust, or the earth and moon formed together out of the primordial nebula.
impact theory
An early collision by (proto) Earth with a large protoplanet..
Scientists n there theories are uncertain still of how the moon formed about'

That is was a captured asteroid, it broke away from the earth after a huge impact, that it formed at the same time as the earth.
Which answer is not one of the three theories of the moon formation; 1. capture 2. parent-child co-creation 3. daughter 4. exsanquination It's difficult to read the original question, what with the lack of punctuation inherent to Wikianswers and the run-together phrasing, so perhaps I have misinterpreted the question. However; "Exsanguination" means "Bleeding". This is DEFINITELY not one of the theories of the formation of the Moon. Of course, none of the other options appear to be correct, either. The "Capture" and "co-formation" theories have been widely discredited, and the most popular explanation is that another planet, perhaps as large as Mars, collided with the nascent Earth, and that the Moon is made up of a combination of the remnants of that other body and the impact debris thrown off by the Earth.
There are no exact theories on the formation of a moon, however, some suggest that a moon such as Callisto would have been created from loose debris in the early Solar System captured by the gravitational pull of early Jupiter.
Do you mean the formation of the Earth? If so, the two competing theories are creation and evolution, as in the formation of the observable universe by the Big Bang.
