Lets see if we can figure out what is actually bieng asked here?

Heavens?
Do you mean the perverbial paradise of biblical note, or the observable night sky?

Looked up?
Do you mean "physically" lifting our heads and looking up, or do you mean pondering what it all means?

God?
Do you mean the creation entity of myth, or the combination of phenomenon needed for matter and energy(same thing) to induce a physical universe?

If you mean the first parts of each question, then the answer is likely no. As it would require humankind observing the heavens to make up such a wonderful story.

If you mean the latter parts of each question, then Yes. As the universe would exist whether we looked at it, or not.
