Yes I think extraterrestrial life exists, but I think this is a question that will not be solved within this generation's lifetime. I feel that everyday people are making prgoress towards discovery and wolrd-wide acceptance of E.T. Even though the accomplishments SETI@home has gathered in this vast universe are mere drops in a bucket, these drops eventually add up.
