The idea that there has to be observers observing things. No, there doesn't have to be observers observing (or measuring) things.
The only thing required for wavefunction collapse is an interaction. Neither of the entities that interact have to be "observers", or worse yet, "conscious" or anything like it.
The thing is, you can't prove that anything has interacted/happened until you've observed it to have done so. There's no knowledge of the world derived independently of observation.
The thing is we have things like camera's and other methods to record events we haven't observed directly.
