Imagine you’re in a big ocean. You look out to your horizon. You realize that you’re in the center of the circle of that horizon.

Does that imply you are in the precise middle of the ocean? No.

You are always center of the horizon since you yourself made the horizon.

We are at the center of the universe we see.

Or.

The universe we live on is the surface of an inflating balloon. Where is the center of that universe on the surface of that balloon. It’s a meaningless/impossible question to answer other than saying the center is where you are or there is no center.
