    Couldn't be. Someone said the moon has been slowly moving away from the Earth each year at a constant rate. If this has been happening for 4 B yrs, then it would have had to be touching Earth to be where it is now. It means your assumptions about how old the Earth and universe are wrong.

    That rate isn't, nor has it ever has been, constant. When the moon first formed, it was much closer to the earth. As the earth and moon cooled and solidified, the orbits became more stable.

    It's possible that if the moon and/or its orbit were different, we couldn't have evolved on this planet to adapt to it.

    Also, I'm thinking it might matter if the far part of the moon's orbit placed it closer to the sun or farther away from it. If it placed it closer, perhaps the sun's gravitational pull might gradually bring it closer and closer the sun. If it was flying further away from the sun, it would partially obscure the sun when closest to the earth.

    That depends on how fast it has been drifting away.

    Yes. If things were different, things would be different.

    That's absurd.

    You're trolling. We are "fine tuned" to the environment in which we evolved. That environment is on Earth's surface.

    We are fine tuned to the environment we live in as a result of evolution, except the environment we live in is extremely hospitable to the potential for life to evolve and fine-tune itself. I personally believe it is more far likely to be pure chance, rather than any type of divine intervention by some hypothetical man in the sky we can't verify the existence of.

    That's very possible. A less stable Earth could mean we would have evolved very, very differently, or not at all.

    Of course, if we did, we wouldn't be here to speculate it.
