Man created God in his image makes much more sense than God created Man in his image.
We are not an image of God ... we are an image of a primate. We are animals. Our speciality in the animal kingdom is something we uniquely developed - not larger claws or speed or camouflage but culture .... 'God' is part of culture, not nature (i.e. nature extended to any thing natural including cosmos and physics).
I like the " reflections of the moral templates both good and bad of the inventing culture" definition. That is an important cultural function; we can call it the super-ego or dress it up as a Goddess and call her Ma'at - being flamboyant, creative, artistic creatures, that works best (at times), through symbol and analogy I find that quiet acceptable - whatever works. Sociocultural change and evolution is best sealed via 'spiritual' revelation, whether by prophet, priest or shaman. 'Terrestrial based' revelation does not seem to have a lasting effect (e.g. communism - hopefully capitalism wont either).
As far as the 'running of the Universe' goes, it actually makes no difference to us if God exists or not.
Why does anyone need to be 'in charge' . Who is 'in charge' of nature ? The lion, Pan, Dancing Animal Master ? Its not that simple ... 'in charge' is a concept .... I suppose it could be extended 'philosophically' to "God is the big alpha-male" but the more I think about that the more ridiculous it seems.
However I do believe there must be a regulating principle in life and the more I study that, the more I am lead into certain mysteries about evolution and the genetic code. There does seem to be 'regulating' principles in genetics that lead to greater purposes and this is reflected in cultural evolution; an expression of some type of 'consciousness' of life ... or 'behind' life.
'Another place after death' ... why would someone need to 'be in charge' of that? Again, most of our ponderings about what is behind life (and death) are extensions of local cultural social patterns .... it all started with the idea that the King was an incarnation of God (in ancient Egypt) - tribal people dont have A person in charge of the afterlife .... there are 'the ancestors'; a multiple concept ... I have never heard of A ancestor in charge of the afterlife.... its a matrix, and that is also a reflection of how they see their lives; a PART of nature ... not in charge of nature .
Perhaps our biggest problem is we think WE are in charge ? Who gave us the right to treat our environment and the other animals the way we do ? God apparently (in Genesis; "And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth." )
Subdue and dominate ... ? If anything WE (think we) are in charge and since 'Man is made in Gods image' - we, in a classical mythological inversion process made God in our image and then we (as God) gave ourselves a divine right to **** up the very things that our survival depends on .... what a mess !
