Breaking the law of conservation. We (humans) are able to do that (little black holes in accelerators). Contrary to what you think God is not the only one who can break the physical laws of nature.
I don't believe that God "move molecules" in this world beside some rare miracles here and there. Most of the time he just change lives like he did with mine.
Why would God not "move molecules" to heal amputees? I believe because that move would have consequences worst than someone living without a limb.
You have yet to address why god is okay with "moving some molecules" so other living things can grow back severed limbs but not humans. And why god "moves some molecules" so we can cut off other parts (hair, etc) and have them grow back without endangering the universe. Also, when humans figure out how to "move some molecules" and use stem cells or whatever to grow back human limbs, will it destroy the universe? If not (and it will not) why can't god rearrange some molecules and do that now?
This being wants people bowing down in worship, and all it can do is give you some nice feelings about yourself and make a bus run on time? Once every few billion prayers, it throws in a random event that people don't understand, I mean a "miracle". It is "undetectable and immaterial" (ie "nonexistent") so it cannot even show up in a physical form so everyone, even atheists, can detect it and decide whether it is worthy of worship or not.
You keep telling us he is the most powerful being ever, the best and smartest and of all, creator of everything, capable of anything, maker of miracles.
Then, when we start asking for some specifics, we get a lot of hemming and hawing and excuses and maybes about how if god actually showed up in an unmistakeable form and did anything, well, godly, it would turn out soooo badly that we would really regret it. So we need to shut up, stop asking stupid questions, quit peeking behind the curtain, and get back to praying.
You realize, Lukvance, you have drastically reduced your god to nothing more than a con man in a dream.
Have you seen this movie? Might be worth a looky.
BTW, this humorously critical "review" could just as easily be used to take apart YOUR ILLOGICAL RELIGIOUS BELIEFS!!!!!!111!!!1
