You can talk and throw all the scientific mumbo jumbo you like. I still say we are not alone in the universe, regardless of what the scientists may say. Scientists DO NOT KNOW EVERYTHING, so they could be wrong. It's that plain and simple. Besides, what they tell us, is nothing more than their conclusions based their study of their field of science and many scientists studying the same field, disagree. How can that be? After all, they are studying the same thing. :-?

So the scientists may be right, or they may be wrong, but we'll only know if and when we eventually make contact with them. In the mean time, I'm on the side that there is life on other planets, in other solar systems, in other galaxies, that we don't even know about yet. Chances are that we will have destroyed this planet and ourselves before that happens.
