It may sound silly, but the answer is that the moon is bright because the night is dark.
Here's what that means: The reflectivity of the moon is only seven percent (7%), meaning that it reflects 7% of the suns light. That may not sound like much, but remember two things:
a) The sun is very, very bright, and
b) The background of the night sky is very dark.
So the moon appears as a very bright luminous disk against the dark background. It reflects light, and on a really bright moonlit night, the world around you seems pretty brightly illuminated. But actually, if you compare the brightness of a moonlit night to daylight, for example by trying to read small print in a book, you will realize it really is pretty dim compared to daylight.
By the way, astronomers call the reflectivity of a non-luminous celestial object like a planet or moon the ALBEDO, which is a Spanish word that means "whiteness." it is stated as a percentage of the brightness of the sun's rays at the object's distance from the sun.
Venus, for example, is much closer to the sun than we are, and its albedo is much higher than the moon's (about 50%), so it appears very bright in the dark sky. There are several ways of calculating albedo, so you will also find other numbers for various objects.
Have fun.

The moon reflects light from the Sun. It is bright because the minerals on the surface have a high albedo, high reflectivity.
As for walking on the Moon, which did happen, when someone is on the Moon he is standing on a very tiny part of it. When you stand on the Earth, it has to be a very bright, very hot day before you are aware that the Earth is reflecting sunlight. But if you were in space and looked at the Earth (or look at a picture taken in space) you will see that the Earth is BRILLIANT.

The moon is bright because it reflects sunlight off the surface which we see. It doesn't shine at all. It is made up of silica which reflects sunlight off of it. It has no atmosphere to difuse light so, even though it is "daylight" on the moon. Stars and the "night" sky would still be visible.

the moon is bright because the moon is basically a reflector.It reflects light from the sun and since it has a white color, that makes a good reflector..

The moon merely reflects the mild of the sunlight. It also seems vivid because this is the brightest merchandise contained in the evening sky for the celebs, that are drastically brighter considering they offer off their own mild, are too faraway from us.

because it reflects sunlight, and because it is so near to the earth

Because it is artificially lit by illuminati arseholes.
