I understand your concern ...
I have every confidence things are happening as they should (which includes the book called the bible), nothing out of order, nothing out of place, all to the end God sent forth his word to accomplish, which which all are in integral part of, perceived or not.
The God at the beginning of the bible is not God, it is our perception of God which is relative to us.
We understand him by his Word, just as we understand each other.
A serpent is inherent in the book (through perception), it's very design is to cause us to reason with God until you become God (which is an unending experience as an absolute in the form of love; and this collectively).
God to us is a word, which leads us back to the word God is.
