My driving reason for this theory is that humans are somehow guided through life processes not dissimilar to those of a spider, but yet somehow our conscious 'we' is not very aware of the directions somehow being followed. There is a part of our brain which is pushing us through our human life phases - so god enters. Note that the sub-conscious builds the virtual reality that our conscious lives in, and so the sub-conscious is in fact 'all-powerful' as well as ancient and loving.

I have used god as the construct to appeal to those facing Christian/Jewish/Muslim religions, but other religious threads have multi-gods and/or multi-spirits. Even Jewish derived religions do not spurn the devil and other spirits. All these are slightly different constructs to better live with the sub-conscious. God/the spirit world is not pure invention, it is trying to attach a label to what humans actually experience from their sub-conscious.

Do you have more information about spiders? How can one have a subconscious without a conscious?
Having now read a bit of Freud, I better understand your comment. However I would argue that whilst Freud was the first psychologist and he went where no man had been before, our understanding has progressed beyond his 'first-cut' id (or unconscious). For instance, behaviours encouraged by our unconscious include group behaviour, pair-bonding and child support. Also I think some of Freud's conclusions were biassed because as a psychologist doctor he was seeing sick people regularly. Consciousness may have arisen as a way of dealing with the huge number of behavioural possibilities being generated by complex unconsciouses.
