It is not enough to imagine that something could happen- you have to show that it did happen. And if you can show that it did, your workings have to overcome the other vast mounds of independently verified corroborating evidence.
My approach is to show "what could NOT have happened." If I prove enough IMPOSSIBILITIES - even the Mighty Apollo cannot Break Physics. Once you show Physics being broken, it compels the physicists to open their minds to the likelihood that what they previously believed, may simply not be true.
You cannot prove a negative.
Here's the thing -- if you want to claim that lunar surface activities were filmed on a stage, that astronauts were suspended from wire rigs to fake lunar gravity, etc., then you have to provide
positive evidence
for those things -- pictures, drawings, invoices for materials and labor (there would have to be a paper trail), etc. You need to show us pictures from "backstage" showing these rigs to fake surface activities (and no, I'm not talking about simulators or trainers, I'm talking about stuff used
during the missions).
If you want to claim the lunar samples aren't genuine, then you have to supply
positive evidence
for that position -- who made them, where were they made, how were they made, how have they managed to fool several generations of planetary scientists from around the world, etc. If you want to claim samples are genuine but were gathered by an unmanned system, again, you have to provide
positive evidence
for that unmanned system -- pictures, drawings, mission plans, etc.
If you want to claim the telemetry is fake, then you have to supply
positive evidence
for that position. What was the source, who programmed it, how was it transmitted in such a way that it
appeared to come from the Moon, etc.
If you want to claim eyewitnesses lied about what they observed, then you have to supply
positive evidence
for that claim. If they were paid off, show us the money.
This is the kind of stuff
you have to provide to make your case that the landings were faked. Everything else is simply gainsaying the published record, which doesn't
prove anything except that you don't believe (or understand) it.
Otherwise this is just a waste of everyone's time.
Any idiot can tweak curves in Photoshop (on a heavily compressed JPEG, no less); whole legions of skeptics and deniers have repeatedly demonstrated that they don't understand anything about photography, or physics, or orbital mechanics, or rocket propulsion, or radio, etc. You're not "proving" anything; you're just regurgitating the same tired talking points which have been rebutted time and time and time and time again.
Find some
positive evidence for your position.
