Argument 3: Apollo Earth Footage
No response at the moment. Most I can say is that most of the conclusions of speculation.
Argument 4: Cross hairs
In the photos where the cross hairs are covered, it is behind a bright white object. In film, bright white bleeds, especially onto adjacent black parts. Therefore the object was not in front of the cross hairs, but instead the white part bled over the black.
As for why they are there, the can help measure somewhat. And plus, this really isn't even a disproof. So what if we don't know the exact reason for the cross hairs?
If you have two photos of the same object, you could use the cross hairs to measure distances.
Argument 5: Shadows
In the photo with the LEM, the shadow of the LEM cannot be accurately calculated. IT does not have to be due east, in the 2D photo, the shadow of the LEM could easily be at the same angle as the rocks, you just can't tell at the distance. The lines drawn are just rough guesses. The LEM shadow could be facing at an angle, it just looks horizontal because of the distance, so the angle in the photo is distorted on the 2D photograph.
Again, it can be easily be seen in the digging picture that the rocks' shadows could be easily going in the same direction as the astronauts, the horizontal line is just a guess. Also, he rock is blocking part of its shadow. Also, we don not know the exact shape of the rocks, and from the 2D picture, cannot tell the exact type of shadow they would cast or if th shadow is hidden by the rock itself.
