You ask the question as if there is only one way to conceive of God, when, in fact, there are many; mine just being one. When one says, "...have a hand in it ..." it implies an active, thinking God, separate from what was created, i.e., the Christian concept.
Mine is a form of Pantheism/Hindu, which views God as the origin of all that there is, God is the template from which all things were created at the moment of the Big Bang, the creation of the Universe, the latest estimate being 13.75 +/- .11 billion years ago. From that instant forward, the template was followed, one of the things being the creation of life.
The conundrum is that whether you accept the Christian version or my version or any other version, you are stuck with the question of "Who created God?" The only possible answer our minds can only partially conceive of is "God created God"; which isn't a satifactory answer, is it? I like my version because it makes logical sense and there are no internal contradictions as there is in the Christian version.
