Non-carbon life forms are pretty unlikely. Carbon is the only element that naturally forms long polymers like DNA. Silicon in the next element down in the same column in the periodic table, but it forms relatively simple compounds at high temperatures. Think rocks. Non-water based life is a better bet. If you are thinking artificial life, well yes, just wait a while and we'll cook up some ourselves, roomba's big brother.
