Are we now God?

Was reading a SF novel (Sister Alice, by Robert Reed) that was taking place millions of years from now, where humans have complete control over their genetic makeup and the more advanced ones can change at will. These very powerful people are revered as gods by their fellow human beings. This made me think about how we "define" a god or at least an omnipotent god. I suppose that an omnipotent god or being is someone who has the power of creating and destroying life (and in general anything that we can sense) at will, and to change and affect existing life in any way he or she sees fit. Humans has always looked to these gods to explain things they did not understand or whenever they wanted to influence other people(notably priests), saying it is the will of God that you must do so and so. In previous times people accepted this and acknowledged the priests making these claims, I suppose mainly out of fear or lack of knowledge to contradict the priests. In more recent times we see people rejecting the priests because they have the knowledge (and confidence) to contradict them. Now back to my main point. If gods are the ultimate creator and destructor of life will any human that achieves these powers then automatically become a God? All through time, humans have seeked technology aimed at destroying their enemies (whoever they might be) and we have become pretty good at it! With the invention of nuclear weapons, we have almost achieved the ultimate power of destruction of life. Granted, the technology is now available to everyone, but it becomes easier and easier as this knowledge becomes more readily available. Also within the last 10-20 years, genetic technology has taken quantum leaps in understanding the building blocks of life and it is quite obvious, that it is just a matter of time before we can manipulate life at a genetic level. So when do we all become gods? Humans has technology now, that can destroy life and create life. Maybe the technology is still a bit crude, but I have no doubt that it will be further developed and refined, even though there are political and religious objections. And when that happens and this technology becomes readily available are we then all gods? In the book I mentioned, humans are virtually immortal and their bodies can repair any physical harm they might find, and I guess that with advances in genetics that is definitely achievable. When we all become immortal will that then spin off a race to find ever more powerful weapons to fuel the desire (or need) to kill each other or will we finally realise that it is a futile effort to keep on killing each other? In the end of the day, nature will always win! And to the people that believe that genetic manipulation is unnatural, I must say that they are contradicting themselves...If humans are part of nature, then it must follow that all we do is also natural and part of a natural evolution...
