Observation doesn't mean a person (or anything) viewing a thing. It basically means that one particle interacts with another particle, affecting it in some way. And so that particle has been 'observed'. It doesn't mean something only exists if we see it. If you want to use your eyes as an example, imagine a photon careening through space just to stop inside your eyeball. You just observed it, altering it's trajectory. You don't even need to be conscious for it to have been observed, the particles that make up your eye did that for you. I'm probably not making that very clear, but I suggest learning more about observation in the quantum mechanical sense. It's not what you think.
