They aren’t being pulled any which way. They are settling is a way to think about it. My problem with gravity is that they use it to how it fits in our perceived reality. Things we can actually see. Then they put it outside of our reality and claim that math works and it’s a done deal. They never prove it. I’m not saying the earth is flat. I am somewhere between NASA and Flat Earth. I don’t have all the answers because I don’t get to study these things myself. Many things other than gravity don’t add up and are taken as gospel. Like how can earth have a molten core that produces magnetism. Nothing else in the universe besides planets and stars apparently can produce magnetism and be molten. You or I can’t prove that one bit. So we are left with believe an organization started by Nazis or trust our eyes and what we can prove.

I guess another way to answer your question is that we are a mixture of various types of matter. The way it works is that we have muscles and bones and water holding us up. That puts us between air and ground density. Water is different because of people’s body mass but water between ground and air. So more dense is below our feet and less dense is above our heads.
