Universe from Nothing?

[Esquilax]

Not sure this is a cohesive argument. Would you agree that designed things display ordered, informational content that often contrasts to the immediate environment?

It depends on what you mean by information, really: in certain usages of the term, everything has ordered informational content, with regards to its position and current state. That's the thing: when creationists talk about "information," it's always this vague term, where it's used more to evoke the idea that the thing containing it is designed, without ever giving it a definition. So, what do you mean?

Besides, my point was that, in a world where god designed everything and fine tuned the world, there can be no contrast between designed/undesigned things, because in that world, everything was designed. The contrast you're seeking is god designed versus human designed, and what would the point of comparison be there? Well, it'd have to be whether the thing looks obviously designed, like the sandcastle above, or things that don't, but must be because of fine tuning. The entire argument is an exercise in question begging.

How would a materialist begin, if not with nothing?

What makes you think we're materialists?
