Yes, I do see the problem. It’s like I explained, since you can’t very well take a picture showing both the earth and moon side by side like that, how are you going to compare the apparent sizes accurately?
The only way to do that would be to take the photos under certain careful conditions, like taking photos from the earth and moon at the same time, with the same kinds of cameras and lenses, and making sure that you have some kind of landmark in both photos so that we have some means to judge angular distances. Just picking a random picture of the earth from the moon, and a random picture of the moon from the earth doesn’t actually tell you anything useful, since you are not making a scientific comparison and you have no context in which to judge most of the relevant factors.
Now, why hasn’t NASA or some other outfit done that? Probably because they all know the earth isn’t flat and what size the moon and earth are, so there is no actual knowledge to be gained from doing that type of exercise, so no scientist is going to waste their time and precious research dollars to do it.
Standard non-answer to a question that wasn't asked.
I have never stated the earth is flat but you keep saying that in order to not have to answer the real question.
Do you really think that no real questions could be answered by gathering data from a camera continually transmitting data to earth about earth from the moon? Why don't we have the same material they used to insulate the astronauts available in our homes? Or why don't we have the heating and cooling unit they used available for our use? You know the one that ran on a few batteries for days, could solve the fake global warming crisis over night.
