Among other things, they were able to discover the geological make up, the age, and the most likely origin of the moon.
Rocks identified as the moons original crust (specifically the Genesis rock from Apollo 16) matched exactly rocks of the same age found here on Earth. This has gone a long way towards proving the moon was formed ~4.5 billion years ago when a Mars sized planetoid struck the still-cooling earth, throwing billions of tons of rock into space. That rock eventually coalesced into our closest neighbor.
They brought back samples of lunar rocks so the scientist's could determine the age of the moon.
Several things: * The age of the Moon * The composition of the Moon * A new theory of the origin of the Moon where developed

Apollo 13 proved to the world that a damaged spacecraft can be brought back to earth, with the astronauts safe.
Apollo 13 astronauts were brought back safe to earth, and the only person of the three astronauts to die is John, jack Swigert, he died in 1983 of bone marrow cancer.
Apollo astronauts conducted and deployed many scientific experiments prepared by scientists on earth. For those with an interest in the results, see the related link below. Many soil and rock samples were taken and returned to earth for analysis.
They performed geological and chemical analysis of the samples.

The two things brought back to earth by Apollo 11 were moon stones and moon dust.

The difference of the apollo 11 astronauts wand the Apollo 17 astronaut was that in Apollo 17 astronaut Harrison Schmitt was a scientist, while All in the Apollo 11 were astronauts.
Not sure Apollo II did, I think it was later flights, but yes they brought rocks back. Even to day some have never been analyzed.
The astronauts entered the Apollo spacecraft by a hatch.
Yes. As well as the video evidence the astronauts brought back moon rocks for scientists to analyse. They left a gold plaque with a quote on and the bottom half of the lunar lander both of which are still on the moon. They should be easy to find with a probe or if astronauts go again in the future and can corroborate the astronauts story.
