Yes, sorry, I misunderstood.
Anyway, pretty much anything that 'Intelligent Design' puts forward has been covered here against Creationism. Intelligent Design is just Creationism with a whole load of irrelevant scientific jargon pelted at it for good measure. It's just as much a non-theory as Creationism. Intelligent Design is for Creationists that want to have some facade of looking 'scientific'.
A lot of Creationists (I shall refer to Intelligent Design as Creationism as well) like to use the argument that the Universe must be fine-tuned to our survival as the likelihood of a Universe supporting a life is very unlikely to happen 'by itself'. This is the weak anthropic principle, and it's probably the best argument Creationists have going for them.
It has one fairly big logical fallacy, and several other smaller ones.
The big one is, regardless of what the probability is, it happened. This Universe does support life, so the probability of it occuring is not 0 - it's not
impossible for it to all have been a big coincidence (so this doesn't really show that 'God must exist', at best it shows that 'God probably exists'). But if this Universe
didn't support life, then we wouldn't be here talking about it. There might be another Universe that doesn't support life. This isn't it. There might be lots of Universes that don't support life. This one isn't one of them. In terms of us, the Universes that don't support life might as well not exist at all. So, in terms of
us, the probability of a Universe supporting life must be
1.
And it all assumes that the Universal constants came about randomly, it assumes that they
could be different. That is a fairly big assumption, and it hasn't really been justified.
Also, if the Universe
was 'fine-tuned' then life should be much more abundant, rather than being as rare as it appears in this Universe.
The real proof of the existance for God would be if he created life in a Universe that couldn't support life. If we looked at all the constants in the Universe and realised "hey, life shouldn't be able to exist at all in this Universe", that could only that God must exist.
