Well, that’s the main reason this subject is considered taboo, isn’t it. But, I just don’t fully trust everything the government tells me,either. And other astrophysicists much smarter than me have raised similar questions, have they not?
If/when some is able to capture a modern picture showing evidence of our visit, the question will be answered. But the fact even that still can’t be done contributes to the uncertainty.
I’ve already pointed out that the LRO has captured that evidence.
Furthermore, if it was a fake, the USSR would have called it out in no uncertain terms at the time.
