With respect to the why are were here versus there question it basically comes down to the fact that we are where we are and we are not where we are not.
That's right, but this statement has different implications in single or multiple universe theories (even in a single infinite unverse).
In a multiple universe setting all the information you have about yourself and your surroundings doesn't pin you down at one place. There would still be an infinite number copies (who are exactly ''you''). I agree that the different versions of you cannot contact each other but within some theories that predict an infinite universe it would be unnatural to ''cut them away'' by pretending that the predicted infinite universe somehow isn't real far away from here.
In fact before you could even postulate that the different you's were "you" you would need to define exactly what "you" is (or is it are?).
Well, most scientists believe that we are just a combination of the right chemicals and do not invoke supernatural things. So you are a certain combination of atoms. Now certain theories predict that every allowed combination of atoms occurs infinitely often. In fact Vilenkin et al. have shown that the exact history of the entire universe shoud occur infinitely often in his ''eternal inflation theory''.
With respect to simplicity versus complexity as things become more fundamental ... I would suggest that consideration be given to the fact that so far as I know no part of physics can not be correlated with information theory. And I have no reason to believe that the entire universe, as we see it, can not be constructed from zeros and ones. Remember fractals create infinite complexity in finite space. The complexity to which you refer may only be obfuscation. The complexity of all of chemistry comes down to just a handful of very simple statements of fact.
I agree.
