Theism posits a personal being who is utterly intelligent, omniscient, omnipotent and loving. A very modest concept, to be sure. For us, persons are biological beings produced by evolution and many of their features make sense only in the context of evolution. Intelligence, for instance, is an ability that helped us
to survive and to solve problems. When chasing elephants, our slow brains, memory, and time limitations made the "try-and-test" method an inefficient way to hunt (and very dangerous too!).
Intelligence seems to be a feature very appropriate for beings with limited resources inmersed in a dangerous and uncertain environment.

But why should God be intelligent? God doesn't inhabit an environment where she has to fight dangers or predict outcomes. If you have an infinitely fast (or "timeless") brain, you don't need to have a very clever algorithm running in your head, any stupid and inefficient one will do. If you have no memory limitations, you
don't need to find patterns in the data to minimize space storage. If you have no time limitations, you can use the dumbest algorithm of all: try-and-test, until you get the right answer, or even better, get all the answers. You will be certain that one of them is right (at least). If you give a programmer an infinitely fast and memory-limitless computer, you won't get very clever algorithms. (Actually, this is the sort of computer Microsoft had in mind). Why? Because computers can always employ brute force approaches if they have unlimited resources. But then, why would a god need to be intelligent at all? She can always employ several monkeys, working for eternity, generating different universes until you get one good enough. God herself could play the monkey part. And let's not forget the omniscience bit! Can you imagine such a being playing chess against Kasparov? It's not fair, is it? And God wouldn't need to use even a milligram of intelligence, always knowing Kasparov's movement in advance. No need to find regularities in past data to predict future outcomes. This is not necessary when past, "present", and future can all be seen at a glance!

As for omnipotence, well, God doesn't need to know judo or karate either. No need for such clever martial arts, brute force will do. Omni-brute force, in fact.

Why would a god have goals? It makes perfect sense in evolutionary and cultural terms that our goals include having sex, having friends, having enough to eat, having sex, being inquisitive, having sex, etc. But, why would a god have any goal at all? Why would a god want anything? In particular, why would a god want to create a universe with Bill Gates and cockroaches in it? As for love, the only kind of love I know is of evolutionary origin. Why would a god be loving? Looking for a partner? No. Caring for her offspring? No. (So that she can love us? You bet!) As for morality, can you imagine a solitary person being moral? What does morality mean in the absence of a society? Hugging trees? "Love thy neighbor", but God had no noisy neighbors to love!

Intelligence, love, goals, and morality seem quite ungrounded characteristics for a super-person who just sits there on the void timelessly. I believe a reason is required to explain God's features and the concept of evolution provides by far the best explanation
for how this could have happened: God evolved
