No body is questioning that. What is being pointed out is, that it 
doesn't make a difference whether you say that atoms lie within galaxies 
or you say galaxies have atoms in them. It doesn't matter which of the 
items you mention first in defining the relation between the two.

Maybe, but where you put yourself is not determined by such unimportant 
details as to which of the components in a relation you mention first. a 
< b or b > a, are two ways to write the exact same relation and someone 
arguing that there is an important difference because in the first case 
we mention a first while in the second case we mention b first is only 
illustrating his own confusion. And that is essentially
what you are doing.
