For the past couple of weeks, History Channel has been having a show called "Ancient Aliens". Basically, they got a number of so-called "ancient alien theorists" who firmly believe that, based on so-called "convincing" evidence, we had been visited by ET's in ancient times and most of our scientific/technological development has had involvement of these aliens. Every time I watch it, I cannot help but get upset about their so-called arguments. I feel that this would be an interesting topic that many of my fellow forum members would be interested to discuss.
First of all, let me state my own personal view on ET's. Based on the overwhelming statistical probability, I firmly believe that there are lives elsewhere other than Earth in the universe. Many of these lives may be highly intelligent, way more advanced than we are. We have billions of star in our own galaxy, Milky way, and there are billions of known galaxies. It's simply impossible to speculate that we are the only ones.
Now, let's get on to the matter that's more controversial (to me, at least). Has any of these lives visited Earth and HOW can we prove it? It seems that most of "evidence" is derived using process of elimination, which itself in certain circumstances is a powerful analytical tool. With the matter of UFO's, it usually goes like this: someone sees a phenomenon that seems to be controlled by intelligent beings and cannot be identified by the existing physical/chemical theories. Then it is automatically used as an evidence of alien visitation. My view: the process of elimination should NOT be used in attempts to explain an unknown phenomenon. Why? To use the process of elimination, one has to assume that he has ALL the possible options/theories available to him. Then if none of these theories can explain this phenomenon, the conclusion would be that the said phenomenon is not earth-bound and could be an alien-origin. However, the problem is "can we assume that we have ALL the theories that there can be at this time?" I believe that answer is easily "NO". There is still so much for us to learn about our own planet. What we now know, compared to all the natural phenomena existing on Earth, is only like a tip of a HUGE iceberg. A phenomenon may not be explained by the existing theories now, but may well be explained by some new theory 100 years later by the next Newton/Einstein. Just imagine at a time before Newton was born, a number of theories could have existed at the time to explain how an apple could fall to the ground. Using the process of elimination would never get to the correct answer. Why? Because Newton's gravity was not even proposed yet. So the process of elimination should never be used to argue for UFO's or any potentially natural phenomenon.
Next, many ancient alien theorists use many cave drawing and ancient arts as evidence for ancient alien visitation. They argue that our ancestors created these artifacts to commemorate alien visitations that they witnessed. The problem is art is a very subjective matter. Interpreting a piece of art is often dependent on the person's own background and believes. When they say a cave art illustrates an ancient astronaut wearing the whole astronaut suit, I see a medieval knight perhaps wearing a full body armor. Which one is it? No one knows... This is the problem, too much subjectivity. One thing that science hates is subjectivity. And many basic scientific methods have been designed to eliminate subjectivity, such as inclusion of negative/positive controls and designing blinded experiment. So none of the ancient arts should be used as evidence for alien visitations.
Many people feel that some ancient technology is too complex for our primitive ancestors to comprehend. Thus, they must have gotten help from ET's. A good example would be the Egyptian pyramids. Many people sees so many "amazing" things about pyramids that "look too complex and too advanced to be solely a product of ancient humans". I found an interesting trend. This kind of argument is usually made about an artifact made by a civilization that either has extincted or only uses verbal means to carry their legends and myths. Nobody questions how the Great Walls of China was built because the building process was carefully documented, including all the pitfalls and trials and errors. It's easy to tell that these ancient people came up with the technology themselves. When it comes to pyramids, no written records exist to show how they built it, thus giving rise to many speculations, including the possibility of alien help. A piece of technology can look complex, but what is the bench mark for considering it too complex for ancient people?
We have to understand that ancient people did thing differently than us. We now like to develop the theory before designing a product, a kind of top-down approach. Ancient people used a bottom-up approach, simply put: trials and errors. It may be time-consuming, but they got all the time they needed. Many ancient rulers had many servants/slaves whose main job was to think of crazy things to do. For example, a few some toy plane-like artifacts had been found in South America that have been dated to Mayan/Aztec time. Many people immediately argue that this is an evidence of ancient alien visitation since plane wasn't invented until 1900's. But is it possible that some ancient Mayans amazed by how birds fly, as almost all ancient civilizations have been, decided to design something that could fly. So simply using trials and errors, they could come up with something that is aerodynamic. It might have taken them decades to do it, but it is possible that they can do it using trials and errors without understanding any of the underlying mechanisms.
Many hold the notion that some ancient machine is even more advanced than modern ones. Thus, this thing must have been designed with the help of visiting aliens. I think this is also wrong. Like I said above, nowadays, we like to design things in a top-down fashion, meaning that we develop a theory and then design a product according to the said theory. Since our understanding of certain field could be limited, the theory developed could be seriously flawed. Since many physical/chemical theories also depend on mathematical assumptions that are unrealistic, these theories may not even work in the physical world. Thus the products designed used these theories would not work that well. Ancient people mainly used trial and errors. Designer might come up with numerous designs and tested them and modify them. This may take a long time, but is actually the most natural way of doing things. Our own immune system depends almost solely on trial and errors to find antigens and infections and kill bacteria and virus. It may take some time (that's why it takes a few weeks to get better from a cold/flu), but it gets the job done. Evolution itself is also a good example of trial and errors. So it is not surprising that many products designed using this mindset have been good. So even though we now understand WHY we want to do thing in a certain way, our products may/may not be as good as those designed by trial and errors.
I apologize for the long post. So what's my take on this issue? If they want to be recognized as a serious field, they have to do some hard-core science. Find solid evidence of UFO's, not just some fuzzy photos that no one knows what they are. When they find something, don't just say "see, this has to be alien tech because it's too complex to be man-made!" Find solid evidence, meaning show this thing was made by some element that is not found on Earth. For instance, something may contains a type of carbon that has C12/C13/c14 ratio that is different from that found on Earth. This would convincingly and scientifically show this thing could be made by aliens.
