Oh yeah I had a few.

  • That the moon you see during daytime is actually Mars (I then repeated that to my big sister and she believed it for an embarrassingly long amount of time)
  • That the "up" arrows on traffic lights were for planes

Me in the middle of my flight when my plane pauses in midair to wait for a traffic light

Well Mars and The Moon are relatively similar in size compared to The Earth. Mars being about twice the size of The Moon, therefore making Mars roughly 1/2 the size of The Earth, and The Moon roughly 1/3 the size of The Earth.

If Mars happened to be in an orbit roughly 500,000 mi or 800,000 km away from The Earth, it would appear that we would have two "Moons" the size of The Moon to the visible eye, giving the possibility of some absolutely crazy solar eclipse events. I don't think it would even drastically change the tides or the overall gravitational well of The Earth and its various current natural satellites all that much, thanks to the inverse squared law with gravity.

Maybe that was what was going on with several different worlds in SciFi that had multiple massive moons....
