I believe that all of these different forms are also the human mind, but that being said, where would these personality traits stem from if not from the mind? I believe that there was influence. These "gods" Could be GOD in the spirit realm evolving throughout space and time as we continue to evolve and that we are what the spirit/dream realm manifest into. We are more than we know and God made it that way for us to ascend to him with adventure . I believe in something I can't quite define yet, but it's something of a blend between eastern and western philosophy. Western is very left brain and useful for foundation, and creating the lines we walk, but Eastern is very right brain and uses visual stimulation and spiritual science to examine those lines, accept them, and move through them. Together they could show the truth, but really it is all in the mind. Consciously you see it, subconsciously you feel it. The dreams and Gods that are written (like the Greek Gods) you could correlate them not only to personalities, but also to our navigation physically and metaphysically in science. 12 vital organs, possibly 12 distinct personality types, 12 months, 12 hours, 12 disciples, 12 reindeers, 12 days of Christmas, 12 inches in a foot, 12 Main Gods, 12 zodiac signs, and 12 main chakras. The number 12 is only significant for identification, but all speak a message of the same thing, the translation is just different for each.
  
    It's like a song the continues on dynamic and technical as it progresses, then an octave change creates the same with a twist while simultaneously other songs run parallel, perpendicular, overlapping, harmonizing, colliding, splitting, connecting, fading, and never ending until the vibrations and reverberations create light stimuli that creates a similar matrix that manifests into physical matter we call this holographic universe. God just spoke the first note and then his essence began to split into many. The tree of life metaphor. We are all God, but we still have to seek God to tap into God because of how far we evolved from source.

I know the truth is there, but it channels in as fragments. Bittersweet to the hungry soul.
