Who says it is?

Stupid answer above. The moons positioning is very pertinent to the gravitational pull of the earth; controlling the oceans movement Let me pick up something on wikipedia (just in cause you wanted a more extensive explanation) Most of the tidal effects seen on the Earth are caused by the Moon's gravitational pull, with the Sun making only a small contribution. Tidal effects result in an increase of the mean Earth-Moon distance of about 3.8 m per century, or 3.8 cm per year.[48] As a result of the conservation of angular momentum, the increasing semimajor axis of the Moon is accompanied by a gradual slowing of the Earth's rotation by about 0.002 seconds per day per century.[49]

Without the moon, what would hit your eye like a big pizza pie to define amore?

There are those that also say that the Moon gravitationally stabilizes Earth's rotation. These people say that Earth would wobble a lot more than it actually does if we didn't have the Moon. I am not entirely sure that I buy this, but that is outside of my area of expertise.

I gives us a sense of the passage of time (months), a close look at an extra terrestrial body, something to look at during a cold, dark night and inspires poets, artists and scientists alike. Go moon!

Can't have werewolves without em! (to me, that's important, werewolves are freakin awesome)

We need those tides, when the tide goes out the beach is smooth and hard, and we can take our cars and trucks out on the beach. Also it would make that moon phase thing on our weather stations worthless without the moon.

G'day Anonymous, Thank you for your question. For us, it is our only satellite and nearest astronomical object. We can learn a lot from studying it. In the overall scheme of the universe, it isn't but neither is the earth. Regards

The regular daily and monthly phases of the Earth's only satellite, the Moon, have guided farmers for thousands of years. Its effect on Earth's tides, has also been charted by many cultures down through the ages. 70 spacecraft have been sent to the Moon. 12 astronauts have been on its surface and brought back 842 pounds of lunar rocks and soil to our planet. Pleasant weather The presence of the Earth`s satellite stabilizes our planet`s wobble. This has helped the planet to have a much more stable climate over billions of years, which may have affected the development and growth of life on Earth. How did it get here? Where did this satellite come from? It is believed that a Mars-sized body once collided with Earth and the debris from both Earth and the impacting body accumulated to form the Moon. Scientists believe that it was formed approximately 4.5 billion years ago (the age of the oldest collected lunar rocks). When it was formed, its outer layers melted under very high temperatures, forming the lunar crust, probably from a magma ocean. Man in the moon On the Earth, we see the same side of the Moon all the time because it rotates just once on its own axis in the same time that it goes once around Earth. We call that synchronous rotation. Patterns of dark and light features on the nearside look like a "Man in the Moon". The lighter parts are highlands. The dark parts are called maria. These are impact basins that were filled with dark lava between 4 and 2.5 billion years ago. After that, the Earth`s satellite cooled down, and hasn`t changed, except for a steady stream of hits by meteorites and comets. Its surface is charcoal gray, with fine soil. This blanket is called the lunar regolith, a term for debris layers on planetary surfaces. The regolith is thin, ranging from about 2 meters on the youngest maria to 20 meters on the oldest surfaces in the highlands. Eathquakes on our satellite Unlike Earth, this satellite of ours doesn`t have moving crust plates or volcanoes. However, seismometers placed by the Apollo astronauts in the 1970s have recorded small quakes at depths of several hundred kilometers. The quakes are probably triggered by tides produced by Earth's gravitational pull. Small eruptions of gas have also been reported. Local magnetic areas have been detected around craters. A surprising discovery from the tracking of the Lunar Orbiter in the 1960s revealed strong areas of high gravitational acceleration on parts of the surface. In 1998, the Lunar Prospector spacecraft team reported finding water ice at both poles. This is probably from Comet impacts. We still Have a lot to learn about our own satellite. It still has plenty of mysteries to be revealed.

With out it, we would not be here....

Because it gets man interested in going to other planets in space by seeing one so tantalizingly close! It makes us believe there are other planets beside our own. Just as the Sun makes us wonder about other stars! And we reach further and farther out there to learn everything!

I think its that whole...we need it...otherwise we would die..same thing with the sun

If we didn't have a Moon, the global altitude of the ocean would have been different. If you take away the moon, suddenly a lot of water would be redistributed toward the polar regions. Earth would spin much faster without its orbiting moon. That's because the moon's gravity pulls on Earth's oceans. The moon is largely responsible for the tides. The pull of the moon, and ebb and flow of the tides, puts the brakes on Earth's daily rotation. The Moon has been a stabilizing factor for the axis of rotation of the Earth. For this reason, we had much less climatic change than if the Earth had been alone.

What else would we howl at?

It is also very important for romance. This song sums it up. That's amore!

It might have gold in it....

Without the moon, life would be different on the earth. When Theia (search for it on Wikipedia) collided with the earth, it put the earth in motion and also tilted the earth's axis which gives us seasons. Tides, which are caused mainly by the moon, "deposited" sea life on dry land.
