Hicky,
    How can you prove that God does not exit?? You can give your own reasoning, the one that you use to convince yourself that God does not exit. Which is fine but likewise no one can prove to you that God exists. You have to  do your own homework. For example I cannot prove it to you that God exists but rest assured I have proved my self that God exists. Just like when someone takes a unique food that experience cannot be transposed nor transformed. If someone wants to taste that unique food one has to try oneself to get the same experience.
    You speak of Science, Genetics, Cloning and computers and say that because these technologies exist that's why God does not exist!! Think again on how this reasoning can hold ground by analyzing your own statement.
    I have worked very closely with the best world class scientists; in the genetics industry but you will be suprised to know that almost all of them including the top scientists are devout believers of their own religion. I have had numerous discussions with them on the belief (of God) and where they stand. I also want to let you know that I am an Engineer and work with computers day-in-day-out. Profession has nothing to do with the belief that you hold rather it is the choice we make.
    It is a philosophical  matter on how we see the miseries of the world and the difficulties in life, I would like to quote one scientist when we talked about the same thing "it is not meant to be easy"
    Peace...
