    Obligatory music reference:  Christine Lavin’s “If We Had No Moon” http://www.youtube.com/watch?v=YyOyH9u4AdI

    Neil Comins actually wrote a whole book called “What if the Moon didn’t Exist? Voyages to Earths that Might Have Been” – I have a copy which I enjoyed immensely. Contrary the astronomical fine-tuning claims of some ID creationists, he makes a good argument that you can seriously mess with the planet without ruling out complex life. 

    Even so, I thought that he was a little pessimistic at times – for example, he suggests that a moonless world, lacking tidal mixing of the oceans’ chemicals, would have a delayed emergence of life. However, such a world would also have faster winds, leading to more erosion and wind-blown dust (which is important to ocean life even today) as well as stronger wind-driven ocean currents. Might these factors not counter-balance the reduced tidal mixing?

    If we had no moon, then Bill O’Reilly wouldn’t believe in a god.

    Please, take a look at the Gap in the Long Earth :P

  6. Isaac Asimov wrote a brilliant column about this for F&SF, with fascinating exploration of the possible effects on the progress of science vs religion.  Later collected with other essays in:

    If memory serves, a magazine article about twenty years ago said that without the Moon, the Earth’s magnetic field would be much weaker, a hundredth or even a thousandth of what it is with the Moon.  Is that statement accurate?

    One huge shallow swamp with only very primitive life forms. Sort of like New Jersey.

    Strange: I usually look to Balk, at The Awl, for postulations on moonlessness (although, granted, there, it’s more just lunar antipathy).

    The universe is they way that it is because if it weren’t, then we wouldn’t be here to observe it. So says the anthropic principle: http://en.wikipedia.org/wiki/Anthropic_principle

  11. I read a theory that the moon is the difference between Earth and Venus because the Moon sweeps the top of our atmosphere away.

    Mars has a 24-hour day (approximately) with no large moon to explain it. Could it be that the same impact that formed the Moon also spun-up the Earth?
