Not a physicist and my time would be better spent learning phyics than speculation, but:

I like to think it's literally an observation that creates the universe, otherwise the entire universe is just one giant superposition.

An interesting thing is also the Quantum Zeno paradox, in that a consistently observed thing is less likely to do the unlikely (by collapsing the wave function according to the Copenhagen interpretation, many worlds by another).

So: - observers contain the possible states of the universe but only with those which they are consistently interacting with - observers interact and enter superposition with the thing they observe to an outside observer (shrodingers cat) - an observer can only be defined by another observer through observation (when we open the box)

Which leads to: The universe was not created until it was observed to have been created, which is the observer-created universe.
