Technologicaly Advanced Out of Existance

World history can be a very interesting and thought provoking topic.  More so in the areas of archeology and anthropology.  Where did we come from?  There is so much more to human history than just the last 80 years or so that each of us will personally experience.  Things were not always the way they are now and they will not be the same in another 80 years. 

History tells us that at one time people believed the world was flat and if you thought anything different you were formidably ridiculed.  Now it is common knowledge that the earth is not flat nor does it have the sun revolving around it.  Some of the common knowledge of today's society could have gotten you killed if you even mentioned such in days gone by.  Change is inevitable and the knowledge base we have today will not always be an accurate point of reference for future humanity.

When an ancient city is discovered, there is the expectation that the people who occupied the city were less civilized, relative to our current day knowledge base, and based on the fact that they were unable to keep their city from being covered up with thousands of years of dirt.  When looking for proof of advanced technology, some would be looking for DVDs and laptop computers, for example, as evidence of such.  These are items relative to current technological points of reference.  80 years ago no one had even dreamed of a DVD or a laptop computer and would have had a different reference base for forming opinions.  80 years ago, people who might be looking for the ways ancient people communicated would have been looking for writing instruments common to what were known at that time.  Today, we now know that a pencil is not the only way to write or communicate in a written manner.  These examples change the base for comparison that would be considered in deciding whether are not the people of that city had technology.

That strange looking "rock", that was found while digging a drainage ditch in the back yard, could very well be the laptop computer type technology of a previous civilization.  We would not know what it is because we assume that no one before us had technology, and because this tangible piece of evidence can be dismissed as a rock.  Perhaps this rock is an artifact from a previously booming civilization here on earth, that had advanced to the point where they had no need for electrical power lines or roads, for example.  Perhaps they didn't have or need these things to begin with.  Why would a previous civilization have the same means of power and mobilization that we do?  Nature has no set rules about how different civilizations in different eras must evolve in the same manner.

Historic writings, drawings and of course construction, are indicators of past civilizations.  Some of these items suggest the existence of advanced technology but little if anything, that we would perceive as technology, is usually found.  It is the tangible evidence that is being sought out.  The tangible evidence is what we base our perceptions and opinions on.  If the civilization that we currently live in was to somehow cease to exist and 10,000 years later be discovered by another evolved civilization, they would have no idea that we had wireless communications.  The invisible radio waves would be long gone and the source of the transmissions would no longer be transmitting.  They would more than likely come across some well preserved library books and maybe some headstones in a cemetery and that would become their opinion as to the extent of our communication.  We know that forming their opinions about us based on these findings is not true but how would they know that?  Naturally with further studies and investigation they would begin to arrive at different opinions, just as we do today when we study civilizations of the past.

As time passes and technology advances, more facts about life and past life become obvious.  As technology advances, fewer and fewer tangible evidences of many of those technologies, exist.  Could it be possible that the technology used by a civilization could advance to the point of where no evidences of the technology exist?  Again using the wireless communication example, is this not something that is happening before our very eyes, therefore suggesting that it certainly could have happened in the past?
