Re:Why so much disbelief in aliens among scientist (Score 2)

The existence of extraterrestrial life is completely philosophical and hypothetical. Saying that such-a-such scientist does or does not think there is otherworldly life is not proof one way or another, even if that scientist is decorated or the great Hawking, whom I admire. We can discuss the size of the universe, the number of stars and discuss it from a statistical point of view. The math involved does lead to the probable conclusion that extraterrestrial life must exist, but this is again not proof. As for the idea that "galactic spanning civilizations" must be seen from our small rock is human arrogance. There is a strong possibility that such a civilization exists and our current technology simply cannot detect it. As for question of celestial bodies and stellar objects being life forms, we don't know that they are non-sentient. that is a philosophical question of another kind. What definition of life do we use?
