Then again Galileo wouldn't be persecuted for saying that the 'Moon' is a world as anyone without a telescope could see that. The Judeo-Christian religion would just accept it as part of God's creation, the Sun to rule over the day and the 'Moon' to rule the night. They'd see a rotating ball in the heavens, this in turn would make it easier to accept that the Earth is not the center of the Universe. Whether its a world or just a ball is hard for them to say, it would certainly explain the phases quite neatly. In our world, the Moon was thought to be a disk as it did not rotate. I'm assuming history that self repairs for one thing. The D-Day landing on Normandy was dictated by the scheduling of the high tides, specifically the Moon and the Sun had to be on the same side of the Earth, and the shores of France had to be on the opposite side of the Earth facing away from the Moon and the Sun, thise creates a high tide and a moonless night. Perfect conditions for getting the landing boats over all the obstructions and mine the Germans placed there. But the landing happen whenever the tide dictate the should happen, the weather cooperates and things catch up to the way things are supposed to be purely by chance, the people living on this world are none the wise as they all seem like random events to them. You know there is a chance of local time reversals too, a very very very small chance but a chance none the less. If you play a movie backwards of someone diving into a swimming pool, and you had good enough resoulution to see all the molecules bouncing around, you would see no obvious laws of physics being violated, although by pure chance it seems that at times alot of molecules are moving in the same direction, so many in fact that they push the diver out of the swimming pool and cause him to land backwards on the diving board. This is all fiction of course, the imaginary universe I visualize has things set up so they would be convienent to the players when they roll up their characters. If you want to know about the time they come from just look in the history books about the year 1969, everything that doesn't have to do about space travel is approximately the same, and the default assumption is that it is the same. Yes the tides maybe higher, but we can make Florida too a little higher to compensate, all this means is that the beaches are much bigger at low tide, and beach goers have to move there umbrellas and beach towels a bit more so they don't get wet. We raise all those lowlands that would otherwise be flooded at high tide so that they are not. Harbors that carry boats would also have to be deeper so boats don't get grounded at low tide. If there is more erosion then we just assume there is more land to erode before the coastlines reach their present familiar shape. Only the things that have to be different are different, if something could be the same by making a few adjustments to compensate for the different moon, it is then. Its hard to say exactly what changes would be wrought, you can say things would be different but in what way is hard to say. In many cases one change is a good as another and its even possible that there wouldn't be any changes of significance. People on this Earth are just generally aware of the tides and make adjustments in their lives accordingly, they don't build houses too close to the shore at low tide and they move their beach umbrellas around more and get slightly more exercise while doing this.
