What is the purpose of having a moon?

It gives us our months of the year

The moon has a 28-day orbit around the earth so naturally there is a part of that cycle when it will be on the same side of the earth as the sun. Note though that you cannot have a full moon in the sky during the day since a full moon means that the earth, sun and moon all line up. You can have a new moon in the sky during the day since the moon is then between us and the sun and all we see is the dark side.

A full moon occurs when the sun and the moon are on opposite sides of the Earth, so a full moon WILL rise at ABOUT the same time the sun sets.

cause it is the moon in front of him

the moon doesnt have a strong enough graviational field to allow it to retain the necessary atoms/molecules to form an atmosphere

Here's information from NASA.\nhttp://www.nasa.gov/worldbook/moon_worldbook.html\n\nHere's the wikipedia entry,\nhttp://en.wikipedia.org/wiki/Moon

Sean is right but it was manufactured that way as a perfect observation post from the aliens inside it observing us.\n\nthe moon is an artificial satellite and is hollow.

The brightness from the moon is the reflection from the sun, the moon itself doesn't emit any light.  It appears bright because it is close to us, if the stars we see at night were as close as the moon they'd be so bright we'd all be blind, not that it would matter as we'd all be incinerated as well.\n\nI don't really think it's worthy of worship, it's nothing more than a large rock floating around in space - a bit like out own large rock.\n\nAnd the Bible does forbid the worship of anything other than God Himself.

Undoubtedly our moon has been impacted by asteroids and other objects that otherwise would have struck Earth. If the moon wasn't there, then it follows that we might be struck more frequently.

The Moon is Earth's only natural satellite. It has no formal name other than "The Moon", although in English it is occasionally called Luna (Latin for moon), or Selene (Greek for moon), to distinguish it from the generic "moon" (natural satellites of other planets are also called moons). Its symbol is a crescent. The terms lunar, selene/seleno-, and -cynthion (from the Lunar deities Selene and Cynthia) refer to the Moon (aposelene, selenocentric, pericynthion, etc.).\n\nThe average distance from the Moon to the Earth is 384,403 kilometers (238,857 miles). The Moon's diameter is 3,476 kilometres (2,160 mi). Reflected sunlight from the Moon's surface reaches Earth in 1.3 seconds (at the speed of light).\n\nThe first man-made object to land on the Moon was Luna 2 in 1959, the first photographs of the otherwise occluded far side of the Moon were made by Luna 3 in the same year, and the first people to land on the Moon came aboard Apollo 11 in 1969.

The moon's light is actually just a reflection.  The surface of the moon reflects the suns light.  That is why you can have half moons, quarter moons, etc.  The moon itself doesn't produce any light.

It's because your mind sees the moon in proportion to landscape features when it is low.  It's kind of an optical illusion - it's not really bigger but your mind interprets it as bigger.

Yes, the moon is a natural satellite of Earth.

The sun exploding\n\nHumans will reach a technological sophistication where they will be able to prevent the moon from leaving\n\nI don't know if they will be able to prevent the sun from exploding though

Here is a very simple and precise explanation with good illustrations\nhttp://home.hiwaay.net/~krcool/Astro/moon/moonorange/

Well the moons rotation is not a problem because it is tidally locked with the earth. It always has the same face pointing towards to earth.\n\nThere are a few reasons why it isn't practical to use it as a satellite. As has been mentioned above it is expensive to get there, and it is far enough away to have a significant delay in transmission.\n\nApart from that, there is another reason. When we deploy satellites we generally want to have extremely precise orbits. We may want a geostationary orbit, so the satellite is always in the same position relative to the earth, or we may want a satellite that covers the whole earth at one time or another. With the moon we have absolutely no control over its orbit, so unless you're lucky enough to have it in exactly the right orbit for you (highly unlikely), it's pretty useless.

Obviously the moon has to be between the Sun and the\nEarth, so maybe they want you to say, "when the Moon is new".\nNote that this is the *opposite* of a full moon.
