Moon collided with Earth long time ago?

I'm sorry if you'll get pissed off since I have no evidence whatsoever. But I heard a rumour that our moon collided with Earth long time ago. It's a vague memory so I don't remember how long ago, but I would guess before any life existed.

Does anyone know anything about this?

Look up Zacharia Sitchin and Tiamat.

It is the current predominant theory of how the moon was formed.

The prevailing hypothesis today is that the Earth–Moon system formed as a result of a giant impact. A Mars-sized body (labelled "Theia") is believed to have hit the proto-Earth, blasting sufficient material into orbit around the proto-Earth to form the Moon through accretion.[6] As accretion is the process by which all planetary bodies are believed to have formed, giant impacts are thought to have affected most if not all planets. Computer simulations modelling a giant impact are consistent with measurements of the angular momentum of the Earth–Moon system, as well as the small size of the lunar core.[44] Unresolved questions regarding this theory concern the determination of the relative sizes of the proto-Earth and Theia and of how much material from these two bodies formed the Moon.

...or you can go to this website that gives a good overview of the predominant theory on where the Moon came from.

That theory states that early in Earth's formation, it was hit by a relatively large hunk of rock that causde pieces of the earth to be flung into orbit, which came together to form the Moon.

There is an ongoing discussion about where the Moon came from on ATS here:

Ohh okay!! I understand now. It broke and then the broken pieces eventually form our moon?

Thanks for your reply, really interesting(:

The moon was once a PART OF the Earth, as best I understand.

A somewhat unpleasant analogy to this event would be: "Have you ever taken a dump and gotten a little splash back on your backside? Well, that is how the moon was formed. The turd being a large celestial body impacting the water (earth) and the splash back is the moon."

If your computer can handle streaming video you should go to the History Channel then click on video and choose, The Universe. Once that loads choose the episode on the Moon.

It will inform you of the latest prevailing theories.

At least those they are letting us know about

Okay thanks!

Wahahaha that's just nasty;D

When I was in elementary school, way back in the 1950's, the popular theory was that the earth somehow, I can't remember how, was broken up a bit and a section of the earth split off and became the moon and somehow both bodies became round due to grativy. Interesting to think of this now, because I remember how the moon rocks that were brought back to earth weren't exactly the same composition as the earth regarding minerals, etc. I'd like to know more about earth/moon theories myself right now. Ah, perhaps I will do some google research.

The best scientific analogy I've ever heard. I loved it.

Hey, I read about 2/3 of one of his books.

I put it down and never picked it up again once he started talking about the physics of orbital bodies.

He is flat wrong. No chance in hell.

Here is something I thought was pretty cool about the moon, though. (Well Earth is similar but not as noticeable)
Ever wonder why the moon has so many craters? Well, we know WHY it does, but what does it resemble?

A golf ball with dimples. Why are those dimples there? To reduce parabolic drag. Allowing the ball to fly further.

Hey, it could make a good faulty argument for creationists!

Edit for Clarity
