Do we need the moon to survive?

This question is asked a lot, do we need the moon to survive? The Moon is such a familiar presence in the sky that most of us take it for granted. But what if it wasn't where it is now? How would that affect life on Earth?

You may be surprised to find out that, the Earth does not really need the moon. It’s totally reasonable and conceivable that life would be possible on Earth even without the Moon, but things would be significantly different in detail. Some of them would be obvious, some would be a little more subtle, but there would be many impacts that we’d notice if we knew to look for them. Here are a few things that would be different.

-Without the Sun, Moon and Earth, there would be no eclipses. The Sun is constantly shining on Earth, casting a shadow for over a million miles in its wake. However, without our Moon there’d be no object that would pass through the Earth’s shadow; there’d be no lunar eclipses.

-Our tides would be tiny in comparison to what they are now, and they’d be dominated by the Sun. But without any Moon at all, our tide patterns would be much simpler, and only the Sun would contribute anything substantial. So our tides would only be about 40% as large as a typical tide is today.

- Nights would be much, much darker than we’re used to. We have pretty decent night vision, so long as the Moon is out. But without it, our night vision is, well, not very effective.

these are just a few differences that would occur if we were without the Moon.
