Scientists may have discovered the oldest Earth rock ever—on the Moon. A lunar sample returned by the Apollo 14 astronauts may contain a bit of Earth from about 4 billion years ago. The research about this possible relic from the Hadean Earth is published today in the journal Earth and Planetary Science Letters.
An international team of scientists associated with the Center for Lunar Science and Exploration (CLSE), part of NASA's Solar System Exploration Research Virtual Institute, found evidence that the rock was launched from Earth by a large impacting asteroid or comet. This impact jettisoned material through Earth's primitive atmosphere, into space, where it collided with the surface of the Moon (which was three times closer to Earth than it is now) about 4 billion years ago. The rock was subsequently mixed with other lunar surface materials into one sample.

I wouldn't put a hoax of this nature past the USA, but in this case it's legit. My simple rebuttal to anybody doubting the moon landings is this:
Why didn't Soviets say anything? They had the technology to track the rockets (or lack of), to listen in on radio communication (or lack thereof) between the rockets and the ground and doubtless had all sorts of other info from their espionage activities. Basically, if there was any reason to doubt the veracity of the moon landings, the soviets would have had evidence and you can bet your last space-dollar that they would have used it to discredit the USA if they could have. This was the height of the cold war. They would have loved the opportunity to cry foul, but they didn't.

Soviet sent animals around the moon. Did USA, before the Apollo 8? Or did we rely on their findings?

that is a really good question. Why russkies preferred unmanned missions to the moon and shut up about america?
but, if you think about it for a moment...
- no, Ivan Ivanovski, this request from USSR is completely unacceptable under any circumstance!
- will you let me speak with your President? you are probably not cleared up enough.
- WTF? OK, use the secure line (offers the red phone)
- 'hello prez? yeah ivan here. Just to inform you that we are releasing those studio photos outtakes if we don't get our way with this, yeah we're that desperate, OK, it's settled then'
- WTF? do you have naughty photos of the President?
- we have something way bigger. As big as the moon.
