You may be surprised to find out, as I was, that the Earth does not really need the moon. That it was ?perfectly placed to sustain life? turns out to be a load of nonsense. Sure, things would be different, but in a good way, believe it or not. The moon?s mysterious introduction into an earthbound orbit still puzzles scientists, esoteric philosophers and ancient historians alike. While physicists puzzle over the anomalous characteristics of the moon, many ancient tales and writings refer to a time ?before the moon?.
Not the Earth as a planet, but life on Earth, and certainly human civilization, could be in bad shape. Without the moon, we would only have the ocean tides caused by the sun; life would have taken much longer to "crawl" out of the water. Also, the moon stabilizes Earth on its axis; without it Earth would wobble around like a top about to fall over (though it wouldn't actually "fall over"; no place to "fall" to). This wobbling would cause different parts of Earth to be nearer then farther from the sun, the climate would shift unpredictably, and plant life would be very scanty. Trees would probably not exist because their climate wouldn't stay the same long enough for them to reach any age. We probably wouldn't be here, and if we were, how would we develop a civilization since farming from year to year would be next to impossible with the shifting climate. So, the planet would be fine, but life on it would be having a hard time indeed.

It's true, life would be threatened without it. The Moon controls the Earth's rotational speed. Before the Moon was created, the Earth rotated at extreme speeds, with a day lasting 6 hours. Since the Moon was created, it's been slowing down Earth's rotation, which is why a day is 24 hours versus 6. It also acts as a "bodyguard" against incoming asteroids, hence the craters on its surface.
the earth needs the moon too.How about the light at night when there was no moon?It is so dark!.How about the tides that bring fishes to fishermen?The fishermen will lose their job if they cannot catch fish.
The Earth formed 4.56 billion years ago, and the Moon formed about 30 million years later. The Earth is tilted at a 23.5 degree angle on its axis. Our precession is very minimal as the moon enables this stability. If we were to tilt from 20 degrees to 70 degrees as some planets do it makes life nearly unsustainable. Not to mention you see all the craters on the moon. Talk about taking one for the team. While asteroid strikes are less common today due to less debris in a more mature solar system, it does provide some level of protection. Moon help us determine distances in the solar system and the size of celestial objects. More recently, the Moon was the terrain where the space race took place between two political systems, allowing for great technical and scientific achievements. The Moon has inspired humankind to learn how to travel to space, and to bring life beyond Earth’s cradle. Moon had a key role in the emergence of science, and in our understanding of our place in the universe. NOW THINK YOURSELF IS MOON NECESSARY OR NOT?
