Are We Alone in the Universe?

People used to believe that earth is flat. Then they started to believe earth is round. Then they were convinced earth is the centre of the universe. Later on it was the Sun that was the centre. All these ideas prove how deluded people can be. But people lack the information in those times. Only few enthusiastic pioneers were interested what Earth is and knew how to search answer to their questions. In nowadays we have much more information. Yet we still scratch the surface of the knowledge of our Universe but we know much more than 30 years ago. I am amazed why they are still people who believe we are the only thinking creatures in the Universe. For me it is out of question that we are not alone. ET life form exists and I am as sure of this as the Sun rises every day.
