The more complex we find things to be, the more unlikely it is that there was a single original creator with the capacity to deal with the complexity. I think we have long passed the point of no return.
The way I look at it is like this. If god has been involved in the minutiae of the whole of creation it must have taken a lot of effort and thought, computation and clever planning. OK - he's omnipotent apparently. He could create the physical laws but suspend them long enough to work his magic all across the universe without having to break the light speed barrier. (I never heard a creationist deny that the universe is large - but maybe some do.)
But could such a deity possibly be this omnipotent and still not be able to solve the 'sin' problem without having to send himself to earth, to torture and kill himself in a barbaric scape-goat ritual that befits the ignorant thinking of the bronze age more than the wonderful understanding of a super-intelligent all-powerful creator?
Think of the intricacies of setting up the physics of the universe so that the initial physical laws are apparently just right for whatever was coming next. Quite a bit of forethought would have had to go into this. Then to split the universe into tidy chunks, the galaxies, then to structure each of them in subtly different ways just so that his 'ultimate creation', humans, have something to study and explore when they learn to build powerful telescopes. After all, if it was not for this reason, what would have been the point of all that intricate detail?
Not only that, but he set the light going so that it got here just at the right time to make the universe look consistently 'old', when if fact apparently it is quite young. On top of that he set off these photons in exactly the right place so that wherever you look from, consistent images are visible. (In other words he deliberately lied to us.)
Then he orchestrated the detailed design of the solar system in this unremarkable galaxy, making one planet just right for life to thrive, but not skimping on the detail that is built into the other remote planets and their moons, the comets and the asteroids. Even the way that the earth spins gives us day and night, warming and cooling just at the perfect rate. The moon was put there to tell us when to celebrate Easter - and to cause the tides, introducing such a wide range of habitats along the shorelines. He made it look different on the other side, leading to the latest ideas that the earth originally had two moons - for some inescapable reason.
Having made the earth just right, supplying it with exactly the right elements that were needed for biochemistry was quite a chore (because only the right elements will work together - and nothing works as well as carbon). He then built all the micro-structure of life, including the amazing detail in the DNA of each separate creature and planted life almost everywhere. The harder you look, the greater the complexity, but omnipotent god did it all, including planting the 'false evidence' for evolution (in copious quantities)!
We could go on, delving into atomic structure and all the physics that leads to the special features of the electromagnetic spectrum, enabling us, and only us, to identify the different elements from huge distances. Those features obviously bring us back to the paragraph about the galaxies. The details of emission and absorption bands just had to be there so that when his 'favourite creation' learned how to build telescopes and spectrometers they would be able to see the inescapable evidence for an old and expanding universe.
Knowing the myths of Genesis we would obviously suspect that god had been lying to us all along, and thus he could test our faith.
Or am I indulging in shallow thinking again? Maybe there is some theologically sound reason why it is easier to create the complexity and beauty of DNA than to solve the problems of sin and suffering.
Maybe there was even a reason that he tried to pass off the bronze-age notion of the human scape-goat to an iron age audience. But even if it was appropriate for the people of the time - perhaps it was - isn't it about time that he refreshed the message for us? Interestingly this question might not seem logical to christians or muslims because they think they already have the answer. Meanwhile the Jews are patiently waiting for an update on the notion of the nature of god.
I don't think I expect an update soon.
Small note: Thanks to JM for the interesting lunch-time conversation leading to the last paragraph but one!
