I suppose, that the trick here is to state, that not the moon, but the earth rotation relative to the moon causes it, so putting the moon at cause is considered wrong, because its existance alone were not the cause for high and low tides in case both rotations were at synch. It is probably a much more complicated thingy where also the sun and maybe even the planets must be considered if going into the details, but this is another chapter. I experienced once a girl who pointing me to the visible straight beams from earth to sky one can see as result of sunlight coming through the clouds said: "look, along this visible beams the water from the lake wents upwards and builds the clouds". She was very convinced it's true, because she learned it at school, so I had no chance to go the details explaining, that there is no need for the visible straight light beams coming through the holes in the clouds for it. I can imagine, that many believe that the moon is orbiting each day around the earth even if they know, that earth rotates around its own axle and around the sun. Its not that important for them to ask for details, so that is the mechanism how the "lies" are born - caused by lack of the necessity or the laziness to achieve deeper understanding.
