I apologize for asking too many of these questions, but I need to know for sure if I'm doing this right.

"Thus the creation of infinite universes from this world of nothing was prevented."

I'm confused if it is was or were again.
When I say it to myself, I think 'was' sounds better but I don't know if it's grammatically correct since 'infinite universes' is more than one thing? Then it should be were then?

Subjects must agree with their verb. I taught my students to put parentheses around prepositional phrases to help find the subjects.

"Thus the creation (of infinite universes) (from this world) (of nothing) was prevented."

That makes it clear what the subject and correct verb are.
