Your statement makes it obvious that you have decided the Bible is god's word. Why?
At the time the Bible says the world was underneath water during the Flood, we know that Egyptians were SO busy being Egyptian they didn't notice the water and the Great Pyramid had already stood for hundreds of years. If you live in America you can drive and see trees that were three hundred years old during the Flood.
Let's ignore the false assumption inherent in your question (i.e. that of Biblical inspiration).
Which god? And which way of serving?
A Thugee devotee of Kali? Or a priest of Quetzlecotl? Or a Conquistador? Or a Crusader? Or a member of the Holy Inquisiton? Or a Muslim terrorist? Or a Christian terrorist? A member of the US Armed FOrces in th 19th C helping to assert Manifest Destiny? A slave-owning Southerner before the American civil war? A boardmember of Union Carbide/Wallmart? Or a Jain? Bachus? Apollo? The list is endless as I haven't even got onto the Hindu gods yet (but there's only really one of those if you actually know your Vedics)
If Jesus existed and did rail against the ritualistic and formulaic practises of the Pharasees, he would spit in the face of many religionists today. The petty, devisive ignorance of many forms of religions would be anethema to someone who basically told us to be nice to each other.
If god exists, he is not some pissy tribal demon who gives us freewill, punishes all of mankind for using it and takes away perfection and leaves us to show how we do on our own, and then confuses languages the minute humans are peacefully co-operating. Any concept of god needing human worship or creating us as some crutch for divine ego is childish and primative.
If god exists, it's bigger than we can imagine, so big we are probably part of it, not divine, but mundane yet still awesome, a new meaning for an old word and far more wonderful than primative supersticion.
