We could move to another galaxy and pick any planet, and 'observe' the universe, and I would bet our 'conclusions' would be the same.
We might be in some far corner of the Universe (although I doubt it has a corner) and still our conclusion would be the same.
The Universe is larger than our imagination can fathom. If, as we used to be taught, it is infinite, then...
It’s a great big universe
And we’re all really puny.
We’re just tiny little specks
About the size of Mickey Rooney.
It’s big and black and inky
And we are small and dinky
It’s a big universe and we’re not.
