Your opinion on the conversation between Abraham Pais and Einstein?

Not merely the conversation, but the idea behind it.
“I recall that during one walk Einstein suddenly stopped, turned to me and asked whether I really believed that the moon exists only when I look at it.”
-Abraham Pais

The question itself, does the moon exist only when you look at it, challenges the quantum theory in respect to the fact that quantum mechanical things lack objective properties. Momentum, for example.

The famous Erwin's cat paradox is a similar example.

My opinion, after researching for a couple of months, is this.

Although the moon isn't there when nobody is looking, it acts as if it is.

Again, Einstein didn't have any proof, it was simply his belief. Science doesn't give us a complete scope of objective reality.
I'm a bio student, I don't know much about physics except what I learned in four years of high school. I'm wondering what other people's opinion on this is(though not many will bother reading😂.)
