Are we somewhere in the middle of everything?
People tend to "categorize" everything and using two categories is always simplest. No matter what were true about the physics, we would notice that there are somethings smaller than us and some larger- and I think that's about all you are saying.
As for whether we are close to "the galactic world" or "the atomic world", that depends on how you make the calculation. Do you want to compare sizes by subtracting or dividing?
