Fans of science fiction...?

Probably, we will eventually come together as one race in the future assuming we survive that long. Since technology is advancing so rapidly now, it would be tough for each individual civilization to advance without the help of the rest of the world. We may still govern our own territories differently, but there will be a type one language that everyone shares and we will more than likely share our discoveries.

There are several fine science fiction novels and short stories dealing with aspects of religion. For example, The Nine Billion Names of God an The Star, both by Arthur C. Clarke, and If This Goes On, Job: A Comedy of Justice, and Stranger In A Strange Land, all by Robert A. Heinlein

"monolithic society"? As in Stonehenge? Many societies start out as monolithic. Most monoliths were made to track the seasons and they believed that gods were responsible for the seasons. How this pertains to aliens....?

If you are referring to a "monotheistic society" then you are wrong. Using Star Trek as an example, the Vulcan's worshiped the same ancient gods of the Greek/Romans. Or that the Klingon's used to have many gods, but then the first two Klingon hearts turned on their gods and destroyed them all.

You haven't actually done much research have you?

MMmm....I'm not sure I agree with your assertion about "monolithic societies." I recommend you read a good portion of R A Heinlein's works, especially Stranger in a Strange Land and Friday.

The thing about science fiction is that it is always an attempt to critique our current cultural paradigms. The religious monolith you mention in some sci-fi is certainly meant to show the dangers of the unchallanged power of the church (any church). In the same way, technology is often both lauded and criticized in sci-fi.

In Sci-fi writing, depictions of futuristic or alien civilizations often have monolithic religions because there is a popular conception that as civilization advances religions move from polytheistic to monotheistic. Historically religion generally has shifted from animism/shamanism in stone age societies to polytheism in the pre-modern era to monotheism in the present. Of the worlds current major religions: Christianity, Islam, Judaism, Buddhism, and Hinduism, all are monotheistic but Hinduism. Some people simply see polytheism as primitive, probably due to strong pushes by monotheistic religions to label them as low, pagan, heretical, or simple. Ultimately, sci-fi reflects the beliefs of the societies it is written in.

Nope. If there are any alien civilizations they will have a completely different biological heritage and therefore will have a completely different understanding of the universe. I think what you're seeing is more a sign of how human beings think.

One time someone asked the Answer Lady " Why is it that on the Pepsi commercial the old lady says there are twelve puppies but only holds up ten fingers?"

The Answer Lady replied: "Because twelve fingered actresses charge more."

It depends on whether or not these alien civilizations consider architecture to be an integral part of their society.

If they don't, it raises some interesting implications as to the nature of evolution, in regards to how an alien species would evolve the capacity for space flight without mechanical assistance.

edit; excuse me for paying attention to the context the question was originally put in.

p.s; star trek isn't proper science fiction and you know it.

More probable than some of the other stuff I've heard on this board.

I think there is no way to know for sure whether this "alien stereotype" is true until we encounter one, all we can know for sure is that if they find us they are extremely advanced...to the point it would seem like magic to us.
