In my experience, Moon landing deniers usually turn out to be Flat Earth skeptics who eventually warp into fundamentalist Christian creationists. It's a well trodden path.
You say you're open to debate but the topic you want to debate is undebatable. So my position is that we landed on the Moon. In this debate I have thousands of data points collected from research and space institutes all over the planet including physical data.
In the other position, you have to prove that something didn't happen. How is this possible? How do you prove something didn't happen?
So maybe you say NASA faked a photo? OK, let's say that for some reason you believe this, that still doesn't prove they didn't go to the Moon, it proves they faked a photo.
You don't need to debate to show that something didn't happen. You need to explain what did happen which explains every data point that we have from Moon rocks to laser pointing and satellite tracking. You need to explain all of that and what did happen that doesn't include landing on the Moon and how the evidence fits this. Because if this is one of those Kubrick on a soundstage bullshit things, you may as well say we didn't go to the Moon because the Moon isn't real
