Shadows not being parrallel: "THERE WAS MORE THEN ONE LIGHT SOURCE TO MAKE THOSE SHADOWS!"
No, this is a trick of light when shining on objects that are at different distances from the light source and at different elevations relative to the light source.
Astronauts in the shadows being lit up: "IF THERE WAS ONE LIGHT, THEN HOW CAN WE SEE AN ASTRONAUT WHO'S IN THE SHADOW OF THE LANDER?!"
Light reflects off things.. it's a basic property of light that allows us to see. Sometimes, when the light is particularly bright (such as, during the daylight on the moon), the light will bounce several times before it reaches our eye. Light bounced off the luminous ground of the moon, onto the astronaut, into the camera.. It's the same reason that if you're under a beach umbrella you aren't cloaked in utter darkness.
The flag moving: "OMG!! DID YOU GUYS JUST SEE THAT? THE FLAG WAVED! ITS A VACUUM ON THE MOON! THERES NO WAY IT COULD WAVE!"
Yup, it is a vacuum on the moon, but did you know that air resistance is one of the main reasons why flags on earth in teh same situation would stop flapping? Without the air to slow the flag down, it can "wave" for 5-10x longer then it would on earth. Think of flapping one of those paper fans.. On earth, the harder you flap it, the harder it becomes to move.. that's air resistance.. if you did that in a vacuum, you wouldn't feel any pressure against your movement.
No pictures of the stars: "THEY'RE TRYING TO HIDE SOMETHING - WE COULD TELL BY LOOKING AT THE STARS WHERE THEY WERE, SO THEY HID THEM!"
The astronauts didn't go to the moon to take pictures of the stars, they went to the moon to take pictures of the moon. Also, it was daylight when they were taking pictures - the reason the earth's sky is blue in daylight is due to water vapor in the air, and the huge amount of blue water in the oceans. The moon doesn't have either of those things.. just lifeless grey plains.. The daylight sky on the moon is black. The sun is still so bright that you can't see the stars, it's just as bright as on earth, but the sky is black. The cameras were set for daylight to get the best pictures of the moons surface, ergo, the stars didn't appear on the film.
Firm footprints: "WATER IS WHAT MAKES FOOTPRINTS DISTINCT ON EARTH! NO WATER ON THE MOON MEANS THE PICTURE OF THE FOOTPRINT MUST BE A FAKE!!"
Well, the dust on earth is different then the dust on the moon. Dust on the moon is jagged, Dust on earth is smooth. There is also a lot more gravity on the earth, pulling the dust down into a indistinct print. Those two factors (jagged dust keeping its shape easier then earth dust, and lower gravity) allow you to make distinct footprints in moon dust on the moon.
Low Gravity Walking: "THEY COULD HAVE EASILY DONE THAT WITH WIRES! I THINK I CAN SEE THEM EVEN!"
While you can get a jump that looks low-g by using wires, the resulting movement doesn't line up with the footage of the astronauts on the moon. Using planes, and going on a parabolic descent, you can experience low-g, similar to that on the moon, and that action look a lot more similar to the moon footage then using wires.
Our lack of return trips: "IF WE WENT 30 YEARS AGO, WHY DIDN'T WE GO BACK!?"
Well, we did, a couple times, but once we had beaten the russians to the moon, and we were deep in the middle of the cold war, there wasn't money, or real reason to go back to the moon. It was a really really expensive and dangerous proposition to go to the moon, and without any real reason to, it sort of faded away in light of better goals. However, we are having talks of going back to the moon recently, and maybe when our space shuttles get replaced, we'll go back. In the meantime, we have the ISS to work with in space.
