Let me play the devils advocate here...
I have read some interesting research on how humans relay stories. Basically, we fill in the blanks using our personal experience, our memories (which are flawed most of the time), and what we perceive to be true or rational. I'm totally butchering the actual research, but my recollection is that humans are capable of literally inventing facts, and inserting them into the stories we tell, and literally believing those insertions to be true. This is not the same as lying, apparently. Look up Elizabeth Loftus (False Memories) if you want more details.
To me, this is a survival mechanism, in a sense. In other words, we are incapable of recording every single moment, and then relaying the details, so we make logical leaps, and based on some set of cultural and/or social norms, we allow some level of freedom to each individual to grasp the main points, with little concern on the details.
In the stories such as Genesis, I believe this is basically what many consider the inspired word of the god character, as relayed to a human. I think that many believers are happy to accept the story, and do not consider the details as important. In other words, they don't really care. Since God is real, it doesn't matter whether he uttered the words, or simply (apparently) spoke the cosmos into existence. Add to that the fact that all gods are basically anthropomorphized so that mere mortals can identify with the god, and you have the recipe for human gullibility around these stories.
Or, I'm overthinking it...
P.S. If you really think about it, the god character of the Bible - assuming the most popular and common attributes - would have absolutely no reason to need anything. The idea that this god "wanted" or "needed" anything is completely at odds with his most common attributes of power and perfection. Perfection at its ultimate level, requires nothing - no company, no creativity, no worship, nothing. I have just disproved the god of the Bible. Good night.
