Apparently it is some lost ancient planet that is in a different orbit around the sun so we can't see it and it doesn't revolve around the sun like the other planets do... It apparently also collided with out planet to create the moon and was discovered by the oldest civilisation 6000 years ago... What are your thoughts?

I don't want a vague discription of a crap film! I mean the NASA research crap... not something from a film!

Originally, "Planet X" was just the title given to something new before it got a proper name - I think Neptune was called Planet X for a while, and I know Pluto was called that until it was named.
After we found out that Pluto is really small, astronomers started looking for another planet beyond Pluto, because there was a little wobble in Neptune's orbit that could not be explained by the known planets. However, it was later discovered (in the 1990s) that we don't need any new planets to explain Neptune's wobbles, in fact we don't even need Pluto! At this point all serious search for a tenth planet basically stopped, although in reality the search had stopped long before.
Then there are weird hypotheses (I won't call them theories, because "theory" is a special word in science) that come around every now and again about some rogue planet. These ideas have little basis in fact, and there are no observations that suggest there is a rogue planet out there somewhere. It's sometimes neat to think about, but again, we have no observational evidence to support the claims. Velivslofsky's (I know I spelled that wrong!) ideas have all been discredited.
There was an object about 1/2 the diameter of Earth that slammed into Earth as the solar system was forming (or shortly thereafter) that formed the moon, but that object was destroyed in the collision (do a search on "moon formation" for mor info).

You are talking about the theory of Emmanuel Velikovsky (Worlds in Collision) mixed in with a little other fantasy. Velakovsy believed that a planet passed several times close to Earth, in pre-history then later in Biblical times.
The theory that the moon was pulled from the Earth in this kind of near collision actually has some support in serious science. The idea that a planet could conveniently and coincidentally somehow always remain on the other side of the sun until, every once in a while it swings around and comes near is pretty silly if you think about it.
That such a near collision happened in more recent (Biblical) times is possible, but not too likely. Such a cosmic event would cause such geologic upheaval that it's dubious any complex life would have survived.
Whether specifically true or not, such theories are based on the real possibilty of wandering planetary or cometary bodies, possible that is up to the point where they become absurd, such as the Elusive Planet X hidden always on the other side of the sun.

Planet X is what astronomers named a body that is currently orbiting the sun. it orbits outside of pluto and was discovered in the late 90's.
It's basically a big asteroid in the asteroid belt around the planets. it's not technically a planet however, and they're still classifying it.

the name "planet x" was invented to name an unknown planet that would explain the variations in saturn's orbit. astronomers estimated where it should be and soon found uranus. later, when astronomers observed unexplained variations in uranus's orbit they used the name "planet x" again. they soon found neptune. astronomers mistakenly believed they saw unexplained variations in neptunes orbit and again named it "planet x", but they found nothing. today, astronomers do not see any unexplained variations in neptunes orbit today.
"planet x" did not collide with earth. two objects collided very early in the solar system's history and became the earth and moon.

Yes I have heard of it. It was featured in the movie Godzilla vs. Monster Zero.
Plot Synopsis: Aliens from the mysterious Planet X, which resides on the dark side of of Jupiter, come to Earth asking its people to help them save their world from the dreaded King Ghidrah by letting them "borrow" Godzilla and Rodan. The aliens are actually planning to use the three monsters to take over our planet.

yes it is an unknown planet
it orbits the sun
but its orbit is so bit it goes out of the milky way and back in
look at this

I think I remember hearing about it in science class but I never paid that much attention so really I don't know anything about it!
