My own favorite hypothesis goes like this: Our universe is most likely to be the simplest one that contains me (us, observers, conscious beings, whatever your favorite rendition of the anthropic principle). It is not likely to be much larger than necessary for creating me. The reason it is as large as it is, then, is that that's what it takes. The answer, then, is that something like me exists only once. More would be a waste of universal size and/or complexity, and Occam forbids it.

Is this as crazy as it sounds?

That doesn't sound crazy at all. I mean at least not to me. At least not at 1 o'clock in the morning. It sounds like the most likely solution given complexity considerations. It is the most likely Tegmark 4 instance with weights inverse to complexity/size as in Solomonoff induction.

Yeah, pretty much. It would be my default assumption, but only if I was completely ignorant about anything beyond the atmosphere. And if we're going to put ourselves in that position, it's not entirely unreasonable to conclude that Marduk grew the world from a weed.

If you are referring to complexity, then I think it's almost common sense.
