Hi Alea.......
Observational error explains it best..........
Yes planets have moons but nowhere as large as ours,
in relation to the size of Earth....the moon's size is
somewhere between Pluto & Mercury.....
"This is possible because the Moon is ‘exactly’ 1/400th part of the size of the Sun and also that its orbit takes it to a position 1/400th of the distance between the Earth and the Sun. In so large a universe as ours outrageous coincidences are certain to happen"
Perhaps it is just an outrageous coincidence.....but there are
tales of tribes who claimed their ancestors walked the earth
before the moon was in the sky......
Doma.
