Perhaps aliens think the same about us?
I disagree.
I think the fact that we are able to learn
anything about science - much less that we are fairly close to figuring out just about everything - shows that there simply
can't be as much difference between us and an alien race as there is between us an gorillas. You could almost write an equation:
Gorilla knowledge of science (g): 0
Human knowledge of science (h): .9 (fraction of all there is to know)
Alien knowledge of science (a): .999
g/h [is infinite] > a/h
If evolution can make such a difference between species on the same planet, just imagine what difference it can make between species on different planets (with perhaps a billion years more of evolution).
We aren't talking about evolution, we are talking about the ability to gain
knowledge. Knowledge of science, technology, etc. Knowledge progresses
without evolution once a species becomes capable of it. We are capable of it: gorillas are not.
One way or another,
every advanced civilization has to go through the process whereby they start from scratch and over time learn how the universe works. How far we are in that process isn't the point: the point is that we
are in that process and gorillas are not.
If an alien civilization spends a billion years in that process while we have only spent 20,000, we
still have a basis for comparison and something to discuss - their first 20,000 years compared to ours. Gorillas don't have that.
Heres the paper on the gorilla theory:
The paper (I didn't get all the way through it) pursues two separate lines of reasoning:
1. Advanced species may not wish to be detected, so we won't ever detect them.
2. Advanced species could be among us and we wouldn't understand them.
Point 1 is perfectly reasonable and is not what I object to.
Point 2 is logically flawed in several ways. Some are decribed above, but several more:
-First is that gorillas are, most certainly, aware of our existence. The problem is that they are
incapable of communication. They see but do not understand. We don't even have clear proof (enough that a majority of scientists would vote for an affirmative conclusion) that other beings exist, so the question of being able to understand isn't relevant until an alien actually shakes hands with us.
-Scond, we
have made serious attempts to communicate with gorillas (by the way, that fact itself also sets us apart from them). Aliens
have not made similar attempts to communicate with us. So just walking around clueless is not a valid explanation.
There is speculation about other dimensions - even other
universes. Such speculation is useless/irrelevant because even if such things exist, we could not, by definition, ever come into contact with them.
Maybe my point can be put simply as: the fact that we are making the attempt to communicate with other species sets us apart from gorillas and shows that should they exist and desire it, other species could successfully communicate with us.
Consider two scenarios:
Man holds out his hand and says: "Hi, I'm human"
Alien (with his advanced knowledge, he can speak English): "Hi, I'm a Klingon"
