I would say yes they are part of the same universe because if you changed your position it would reveal things you didn’t see before and mask thing you use to see. Not that that is possible yet, but there are no laws of physics preventing it, only our super short live spans.

That’s just it. The laws of physics, at least as far as we understand them, absolutely preclude changing our position in any way that would reveal anything outside our observable universe. Lifespans don’t come into it at all. If you lived forever traveling at the speed of light, you would never achieve that change of position.
The cosmic background is the leftover “noise” of the big bang, and we observe it roughly uniformly in every single direction. So where did the big bang occur? Everywhere. Everything that exists is precisely at the center of the universe, right where the big bang happened.
It’s all about the concept of spacetime. Spacetime isn’t space and time considered together, it’s a singular thing that operates by rules that we are ill equiped to comprehend intuitively.

I do not agree.

The edge of the observable universe is moving away from us faster than the speed of light from our perspective. (Due to space stretching) So we’d need to go faster than the speed of light to catch up.
