A GUIDE TO CRYPTIC THINKING, decoding ciphers, brings the topic of ancient astronaut back to hot.When we talk about ancient astronaut, there is a theory that alien astronaut visited our earth during ancient times and they affected our creation of civilization and humankind as well. Did those alien astronauts help us on the ancient marvels, such as pyramid, Easter Island, or the Nasca Lines in Peru? Were they responsible for the advanced ancient civilizations like Egypt or the Mayans? It is interesting that the mural (painting) recorded the pictures of ancient astronaut used to visit our earth at Mountain Helan in ancient China before 7000 years. The astronaut in the pictures had an armet and sealed clothing, which is very similar to the appearance of our modern astronaut. It was also showed the UFO in the mural. It is assuming the aliens showed up earliest in China. In 1970's, an international sensation was happened by Erich von Deniken caused. He challenged the primitive human constructed the large-stone building by themselves. He imagined the ancient astronaut supporting it. Validated by archaeologists that the large-stone building constructed by primitive human without alien support. But it cannot say giving up to search the possibility of other evidence of ancient astronaut. Published by St. George published. A GUIDE TO CRYPTIC THINKING, incantation of the law against inept critics. There is a section of the book is regarded to ancient astronaut. It takes up the challenge about ancient astronaut. It does not concern with what the alien astronaut did, but care about what they left behind. The way is led by Deception cryptography. May be you would ask, "What is this book talking about?" It covers several categories including science, society, culture, art and etc which linking with archaeoastronomy, astrobiology, planetary astronomy, SETI astronomy, and cosmology. One section is talking about a Nostradamus prophecy of the JFK assassination. One section is showing and reevaluating archaeological imagination. One section is presenting something about a parallel universe and time travel at a velocity of light. One section is sharing us a scheme to pull humankind out of the Dark Ages. One section is concerning a lost book of divine revelation called the Revelations of Elijah and a branch of medieval Judaism know as the Kabbalah as well. One section is referring to rearranging the orbits of the outer spaces. General speaking, this book wants to tell you about the theme of Cryptic thinking. What is Cryptic Thinking? The author explains: "It looks as a tool while decoding some messages which hided by deception cryptography. In some respects, same as the type of thinking, it is needed to construct or solve cryptic challenges just like crossword puzzles, but extends beyond written words to encompass all kinds of ciphers i.e. geometric ciphers, mathematical ciphers, date ciphers, and etc. Obviously, from the view point of St. George, A GUIDE TO CRYPTIC THINKING should not be a conglomerate book about separate and distinct subjects. It may look as an exclusive theme about a fish completely. A single fish from extra solar and come into our solar system 5 hundreds years ago. According to the thinking of St. George, this was not exactly a fish we know normally. It is talent and has multiple functions, i.e. understanding of human language. So, it may be ideal to refer to it as an aquatic alien.
