Why does the structure of the universe, including its physical laws and constants...?

that is the way God does things he speaks then into being and they come into being years after he spoke them into being, God say we as christrian are already seated in heaven with him.

It doesn't.

Take just a second, and look at it from another perspective...

If the universe were significantly different from what it is, you wouldn't be here to wonder about it. It shouldn't be at all surprising or miraculous that a living species that needs certain kinds of matter, certain balancing of forces, liquid water, abundant carbon, and an oxygen atmosphere evolved on a universe that supports those basics, and on a planet that has what we need. We couldn't possibly have evolved anywhere that didn't have those things.

Now, if you want to talk "miraculous" or "improbable:" what would be miraculous would be if we needed an oxygen atmosphere, but were on a planet that didn't naturally have one. Being somewhere we should *not* naturally be able to survive or evolve -- that would be a miracle.

By the way, that "one part in a million" thing for the "fifteen constants" is rubbish. Most of those constants could vary by thousands of times, and there would (probably) still be a universe. It might not be exactly like this one, but there would still be one.

Peace.

It "appears" that way to you because you're looking at it from a human-centric perspective. You're attributing some deeper meaning to our being here than there may actually be.

Sure, as humans, it's natural to assume that we're special, that we're unique, that there's some special plan or purpose to our existence. We all want to feel justified in what we do, and feel as if we're working toward some great cosmic goal. But we might not be. We probably aren't. There's no indication that "human progress" is actually "progressing" toward anything. Heck, we don't even know if we're at the end of things; humanity might just be a stepping stone toward a more thoroughly developed and even more dominant life form.

The universe has no motivation, has no goals, has no intelligence. It cannot prepare. What's wrong with the idea that we're here by lucky happenstance? Is it impossible to enjoy the universe's magnificence without attributing it to some creative intelligence? It's an awe-inspiring place in and of itself, lucky happenstances and all.

Anthropic principle. You can't apply statistical probability to predict something that has already happened (e.g., why did everything work out so perfectly for the Phillies to have won the World Series last year?).

Also according to what we know about quantum mechanics it is entirely probable our universe is just one of an infinite number of universes, each of which has different physical laws. If so, it would be improbable not to have every possible outcome realized.

Because God created the universe that way.

The puddle/hole analogy doesn't apply, and they know it.

Haha, let me ask you this: why is it that God hates the people who live on Mars? ....What's that? There's no people on Mars for God to love? Gee....And there are people here? And the people here think they're special but before and after those people and whereever people AREN'T, they DON'T think they're special? Nevermind, your standard for truth has long been 'whatever keeps away the boogeyman' so I shouldn't waste my time. And yet....I do.

Why does a pothole appear to be perfectly formed for the shape of the puddle it contains?

Logical fallacy detected. Key word: "appear".

If everything was designed for us, why is 99.9999999...% of the universe instantly fatal to mankind?

I forget who said it but: "imagine the puddle thinking the hole its in was designed especially for it".
