Zdad I think you’re alluding to the fact that the earth revolves around the sun.
Even taking that into consideration though, as we humans observe the universe with our eyes or telescopes from here on earth, that makes the earth the center of the universe to us. The universe is vast, and from our perspective we are at the center, even as we seem to revolve around the sun.
The heliocentric diagrams you saw in science class might have helped explain things, but you can place the earth at the center of the diagram too. It’s just like the globe your geography teacher used that always put Antarctica at the bottom; you could put the penguins in the middle or on top and still get a representation of the placement of the continents and oceans.
Am I making you dizzy?
