What’s your definition of the “physical universe” as compared to the “universe”? I’ve never heard the former term used term before.

What happened to the one prayer that Christ taught us: “Thy Kingdom come, Thy will be done, on Earth as it is Heaven?”.

No mention of Mars, is there?

If
you define Universe as meaning "ALL created things," --- in other words, a synonym for "Creation," ---then in addition to the material universe there are also angels -- spiritual entities --- in the Universe.

So when I am not referring to angels, I make that limitation clear by using the term "Physical Universe."

The term "Physical Universe" is commonly used in this sense (LINK)

If
you define "Universe" as being limited to "all MATERIAL created things," then the term "physical" universe would not be needed, it would be be redundant.

The use of the phrase "on earth" neither includes nor excludes the possibility of other inhabited planets.

It's as if one were to pray, "Thy will be done in my household" or "Thy will be done in my heart" --- it doesn't imply that there are no other households or no other hearts.
