The moon is too far for a flag to be seen from the earth. remember that the furtherest object your naked eyes can identfy is at maximum 600m - 800m and the average distance from the Moon to the Earth is 384,401 kilometres .
the reason why you can see a galaxy is because they are very big (light years in diameter) the Equatorial diameter of the moon is only 3,476.2 km[1] (0.273 Earths). Thus the moon is too small when compared with a galaxy.
And with the issue of moon landing I totally agree with your brother, I believe it is a hoax.

There are two reasons which combine to make that flag on the moon not visible from earth:
1. The atmosphere twitches and shimmers and makes pictures fuzzy. No matter how good the telescope is, the fuzzy effect of the atmosphere is going to "erase" the flag.
2. Those galaxies you can see at night all EMIT light. The flag on the moon doesn't. If the flag emitted strong light, the Hubble space telescope (which is above the atmosphere) might be able to see it. Maybe.
But here on the earth at the "bottom" of our atmosphere looking at a small object that doesn't emit light from the moon 241,000 miles away, there's no way to do it.
Those lights from other galaxies are from very big, very bright stars, not little flags.

Jeez, you have to get things in proportion. The Andromeda Galaxy is visible with the naked eye, and covers a larger part of our sky that the moon. So, what you are saying in that context is quite ridiculous.
You also have to bear in mind that no telescope can resolve even the nearest stars into a disk. probably the telescope that could capture flag on the moon would also be able to resolve palnets around the nearer stars - something no telescope can do at present (the planets are detected by other means).
So, there you are. Go away and learn more about astronomy and try to get the scale of things in your head.
And when you have got that knowledge you may be intelligent enough to realise how perfectly ridiculous it is to doubt the moon landings, for that is an example of scale also (400,000 people worked on Apollo - it is nonsense to think someone could introduce a hollywood production without them knowing).
Growing up is having knowledge before you open your mouth.
Grow up.

It's a question of resolution. Distant galaxies will be a big blur in your eyepiece, but at least you can see the galaxy. A flag on the moon would amount to less than pixel. Since one pixel is the smallest denomination of what you can see, you wouldn't be able to resolve something as small as a flag. Not even the Hubble Space Telescope can do that.

Because no telescope made has the resolving power to detect a one-inch diameter flagpole at a quarter of a million miles.
But lots of telescopes can see objects that are tens of millions of light-years in diameter.
I did some calculations a short time ago on the best telescope available -- the Hubble. Not the biggest mirror or aperture, but no atmospheric interferences. According to the Hubble specs, it can resolve an object about 10-20 meters in diameter at the distance of the moon. But the largest object we left behind -- the bottom portion of the LEM -- is only about 4 meters in diameter.

Relatively, the galaxies are much much larger than the flag.

cause they landed on the far side of the moon.. the side which is always turned away from the earth. there is no way of looking at this side unless u go to space again n orbit the moon.
