I hadn't realized that you are not a supporter of Heliocentrism. Sorry about that.
As to the other issue, the inability to show an accurate depiction of the supposed scale of the earth and moon in relation to the sun, well, this issue isn't the same thing at all as not being able to depict an oxygen molecule. We cannot, of course, see molecules at all with the naked eye. We can, however, clearly see the sun and moon.
It isn't reasonable, IMO, to think that the sun is so far away from the earth that it can't possibly be depicted accurately in a drawing of any kind whatsoever.
And we have Sacred Scripture on our side.

An accurate picture of the sun, moon and earth depicted on one page or one computer screen would look like a line going across the page or screen, and would not convey any information. The purpose of the out-of-scale images is to bring the details of the very long reality down to size so its parts can be observed. When we watch an eclipse in person we are seeing the whole picture from the end of the line segment, so we do not observe the length of it because of its foreshortening due to our line of sight. It can be compared to a rifleman sighting a target through a riflescope. What he sees in the scope is an enlarged image of his target, but he cannot see the side view of the bullet's impact. That takes another point of view, at the target. But if we take that same point of view and try to draw in the length of the shot and include the image of the rifleman holding his gun, suddenly the parts of the whole picture become so small on the page that the whole thing would look like a line, conveying no information of the details of the rifle or target.
.
For you to be consistent, you would then say, that since the details of the rifleman and target cannot be given on one page then you do not have to believe that they exist. Does that make any sense?

Or take the finding of the Titanic on the ocean floor. Try to draw a picture of the searching ship on the water's surface, with the cables going down into the depths of the sea, at the end of which is the submersible craft with lights and camera, showing as well the wreck of the Titanic on the ocean floor. Try to fit all that on one page showing details such as the shape of the submersible and identifiable parts of the ship, and don't forget, the length of the cable is over one mile, or 5,280 feet. For you to be consistent, you would have to say that since those details cannot be shown on one page then you don't have to believe they were possible, and that the Titanic was never found or observed as they reported it was.

For something to have happened at a great distance it is not necessary that the whole event must be viewable on one page or one computer screen with an accurate scale image.

Can you show a detailed picture of the airport where you took off, the flight path of the aircraft over hundreds of miles, the airplane you flew on, and the airport you landed, all on one page? If not, then you must not have taken any such flight because it cannot be shown on one page or one computer screen, no?
