a photo of person A does not exclude it from being a photo of person B as well. I see two astronauts. If a caption says there is only one (but does it even stipulate that?) then the caption is incorrect. This is really not a photograph of Armstrong on the Moon? If that's so, who is it standing in that space suit photographed on the Moon? Too old to be Roadster's Starman.

you know who is in the space suit. Everybody does. This is not a space question, but an opinion question.

Is it possible to address the question as asked "...isn't this (a photo of Armstrong on the Moon) also?" directly? My down vote is because the answer seems 1) directed at me personally rather than a statement of fact, and 2) doesn't provide something either close to a boolean yes or no, or explain why for the purposes of a Stack Exchange answer that it can't be determined.

I see your edit, but I still don't understand what aspect of seeing Armstrong in a photograph taken on the Moon is subject to opinion here. While this answer continues to post opinion; "I would describe it as..." replacing "I guess it doesn't..." that doesn't mean that there are not facts available to us here. But posting opinions together with vtc as opinion-based is strange; the idea of vtc as opinion-based is to prevent opinion-based answers from being posted, yet the voter posts opinions as an answer! precisely the thing that the vote is intended to prevent. Something is amiss here...

You have asked an opinion based question - I have voted to close and given you an opinion based answer. Your opinion based answer is the opposite - hence opinion based. Again, I could have voted to close as off topic. Your question is all about how to title a picture. And yet as usual you attack posts that disagree with you.

Close reasons are for questions who's answers are likely to be primarily based. I don't think there's any way to say a question is primarily opinion-based. "This question is likely to be answered with opinions rather than facts and citations. It should be updated so it will lead to fact-based answers." This is why I think that deliberately answering with an opinion then closing for this stated reason feels like a self-fulfilling prophecy, and the answer does precisely what the what the close vote is supposed to prevent. Again, something is amiss here...

But the question is easily answered with fact-based answers as written, an edit is not needed. It's a photograph, Armstrong is in it, and it's on the Moon. Are any of those in any way less than facts? Which one of those is an opinion and not a fact? btw did the close vote come after my down vote of your answer?

The question simply mentions another photo of Armstrong purported to be the only photo of them on the moon. My question asks "is this one also?" I don't know who has or has not challenged anything yet, none of us can evoke "nobody said". However closing a question blocks answerers from having an opportunity say either way.
