There are three theories of the moon's origin:
1) the moon was part of the Earth and broke away early
in the Earth's history due to an impact with a large
meteor or asteroid.
2) the moon formed at the same time as the Earth and
in the same way -- gravitational collapse of a proto-stellar
gas cloud.
3) the moon formed separately and was captured by the Earth's
gravitational field; we suspect this is what happened with
Mars's two moons.
Since the manned-moon landings starting in '69, moon rock
composition being very similar to Earth minerals suggests
that theory 1 or 2 is correct.

There is one main belief among astronomers about the origin of the moon. The theory is that early in its life cycle, the Earth was smashed into by a huge asteroid. Since the Earth didn't yet have any atmosphere and was molten lava basically, a huge section of the Earth supposedly flew out from the impact, and later cooled and solidified to form the Moon. Since Earth is more massive than the moon, it continues to keep the moon in orbit. Since the moon is so close to the earth, it affects the tides. That's all. There is nothing really having to do with magnets or their impact really.

Tides have nothing whatsoever to do with magnetism. Tides are caused by the moon's gravitational pull.
The scientific evidence seems to indicate that the moon was formed from the earth's material, as the result of a collision between earth and a very large asteroid.

The fact that it is gradually moving away from the earth suggests that, long ago it may have been part of the earth, before either of them was much more than a loose collection of rocky iron ore and nickel clumped together and being bombarded by all sorts of comets, meteors and asteroids over and over and over all the time for millions of years.... its not much of a stretch to believe that in the beginning, the Earth and Moon were all a big lump that broke up over time. Lucky for us too... the Moon has a stabilizing effect on our rotation. A wobbly Earth would be a rough place to live.

yes the moon was once a part of earth about 2 billion years ago when earth was still just a ball of hot lava blobbing around space like a aimless air bubble ,when a large meteor hit the earth and its inpack tore a pice of magna out of it and it ended up in an orbit to the earth,this same moment is responsible for the dayly earth rotation around itself and gave it stability in the solarsystem,like a spinningtop,its more stable,when it rotates.eventually the moon will fall back into earth in about 3 billion years give or take a fe billion years.most scientist think this impact created the yearly woble of earthwhich creates our seasons ,but this is bull,there was no seasons untill 65 million years ago when the dinosours got wiped out by a much smaller meteor but still big anough to change our world for ever end giving us this wobble without we would not have any winters

There was a theory about a meteor or and asteroid that crashed into the earth billions of years ago. Then, while the earth was reforming, another chunk of the earth split and moved away. That chunk of the earth was believed to be the moon, and the meteor, or whatever crashed in the earth, became (I think but I'm not sure) the Earth's inner core.

a planet about the size of mars struck the planet at an oblique angle the debris formed the moon outside the Roche radius,the moon gave use our seasons by tilting the earth at 23 degrees ,it also slowed the earth's revolution from about a six hour day to what we have now

The earthand the moon were one.it was hit by an asteriod that they named THEAH....When this happened it broke apart and the moon and the earth were born.....I did some reserch on this as i named my baby daughter THEAH-SAFFRON PHOENIX, all to do with red fire and explosions in a way that is hard to explain.....But that is how the earth and moon came about....

Since it orbits with the earth, isn't it still considered part of the earth?

I think I like your thinking.
It is as good an explanation as any.
There is no real empirical evidence, only theories.
No one has any proof.
That being the case your theory is as good as any.
