Shall I continue or are we just ignoring all the ridiculously important stuff that comes in 1s or other numbers? Just blinkering ourselves to the twos?

How else could either of those systems work then? Apply Occam's Razor. How else can you get the oxygen from air and lose the carbon dioxide without putting it somewhere, processing it and then spitting out the waste?

We breathe in and out because that's the only way breathing makes sense. If we didn't breathe in we couldn't strip the air of its oxygen. If we didn't breathe out, we'd explode after a few minutes. It's obvious, isn't it?

Ancient mystics believed the world was flat and the stars were gods too. Ancient mystics aren't often the best people to consult in 2015, especially when you're going to try and invoke quantum mechanics.

Binary choices are easy to deal with. Our brain likes to be reductive in order to increase efficiency and Yes/No 0/1 Good/Bad choices are the easiest to make. Most things have a conceivable opposite and the diametrically opposed nature of them makes deciding much easier than picking our favourite shade of grey.

There's plenty of non binary choices in human life though. Cherry picking the binary ones isn't really terribly fair. Are the most important jobs we do every day binary? Choosing something to eat from a planet full of choice? Picking a mate from 3.5Bn candidates? Choosing an occupation? A favourite subject? A forum to post your musings to? Favourite colour? Your name?

We're not; it's just a particularly common form of thinking.

A little bit. Our brains are highly evolved to provide us with the simplest view of the world so that we can process such huge amounts of sensory data in such short times. Reducing our choices in some areas to the minimum (you can't have less than two choices) on the more "black and white" issues allows us to spend more time on the choices that exist on "greyer" scales.

No. We found those rules by devising experiments and looking at the results. We know the Universe is expanding because of Red Shift... it's not something we dreamed up, it's something we found out. The same cannot be said of your "ancient mystics".

No. In fact, one of the most basic properties of elemental particles (of which something like 17 types exist), their "spin" is anything but binary.

It's not, but it can be if you blinker yourself to only thinking about binary choices.

Especially if you are only looking for things that fit this mould. Life and Death is easy. How about "Health"? There's not just "Healthy" and "Unhealthy" is there? It's an almost infinitely complex scale for anyone, isn't it? Lots of our qualities are like that.
