Is the Mayan civilization really a civilization left by highly intelligent creatures?

First of all, the Mayan civilization is indeed a high-tech civilization, which I will say slowly. But these civilizations are not necessarily assisted by aliens, but may be the Mayans themselves. You should not simply think that the Mayans were really monkeys in the Stone Age at that time. They may be more advanced than our present technology. From the ruins, we can't verify how advanced the Mayan technology is, because there is no direct evidence to explain it. What I want to say is that mankind has not found any advanced instruments or devices in the Mayan heritage. If there is, things will be easy. The difficulty is that we have found nothing. Pyramid of the sun and the Moon Pyramid and the Road to Death. Pyramid of the sun. Every year at noon on May 19, the sun will shine directly at the top of the pyramid. So is the sun on July 25th. During these two days, the west side of the pyramid will face the sunset, which remains unchanged. On the days of vernal equinox and autumnal equinox, it is even more peculiar, but it is also a specially made effect. At noon that day, the sun moved from hard to north, gradually erasing a straight shadow extending along the lower steps in the west. From dark to bright, the whole process takes 66.6 seconds, just right. Year after year, since the pyramid was built, year after year, until the day when the tower turned to ashes. This means that the pyramid is at least a ten thousand-year clock. Pi and Pi are thought to have been invented by Archimedes in the 3rd century BC, but these values have already been included in the pyramids. The circumference of the pyramid at the base of the sun is 2932.8 feet, and the height of the tower is 233.5 feet. If the height of the tower is 233.5*4PIE, the result will be equal to 2932.76, which is less than 0.5 inch from the circumference of the tower bottom. In order to meet this feature, the angle of the inclined plane of the Mayan pyramid was made into a very special and difficult angle, 43.5 degrees. This is definitely not a coincidence. This is a mathematical language. This is a language that anyone can read at any time. Unbalanced knowledge. 1954, J. Erick Thompson, the authority on archaeological issues in Central America, admitted his confusion when he discovered the obvious contradiction of Mayan civilization. Generally speaking, the level of Mayan civilization is average, but their knowledge of astronomy/calendar is extremely advanced. "Maya intellectuals can draw accurate astronomical maps, but they don't understand the principle of wheels; They are more eager to achieve eternity than any semi-civilized nation, but refuse to take a small step from Liangtuo Arch to Arch. There are millions of them, but they never know how to weigh a bag of corn. " He asked, "What kind of thinking quirk is this?" Maybe the answer is much simpler than Thompson thought. Astronomical knowledge, understanding of time, complicated mathematical calculations, etc. It may not be a "quirk" at all, but a part of a more or less complete, interrelated but distinctive knowledge system inherited by the Mayans from an older and wiser civilization. In this way, the contradictory things observed by Thompson are easy to explain, and there is no need to argue unnecessarily about these things. We already know that the Mayans inherited the Olmec calendar (Olmecs used the same calendar system more than a thousand years ago). The real question should be, where did the Olmecs get this calendar? How high a level of science and technology does a civilization need to invent such an accurate calendar? Take the year of the sun as an example. Modern western countries still use 1582 solar calendar founded in Europe. It was a calendar based on the highest scientific and technological level at that time, namely the famous Gregory calendar. Julian calendar, who was replaced by this calendar, calculated that the earth's cycle around the sun was 365.25 days. Pope Gregory XIII revised it to a more accurate 365.425 days. Due to the scientific progress since 1582, we now know that the exact length of the solar year should be 365.2422 days. The error of Gregorian calendar is only 0.0003 days more. This was quite accurate in the16th century. The Mayan calendar was much earlier than16th century. Its source becomes blurred, but its accuracy is higher. The solar year calculated by it is 365.2420 days, and the error is only 0.0002 days! (10) Aren't you surprised? Similarly, the Mayans knew the period of the moon's orbit around the earth, and they calculated the time as 29.595 days, which is very close to the result calculated by the most sophisticated modern methods. Mayan priests also had precise timetables to predict the times of solar and lunar eclipses. They know that solar and lunar eclipses only occur before and after the intersection (the intersection of the moon and the sun) 18 days. The Mayans were also accomplished mathematicians. They have advanced measuring technology and chessboard computing equipment. It was not until the last century that we discovered (or rediscovered) this method. They are familiar with the abstract concept of zero and its usage, and are proficient in digital counting. Whoever invented the precise calendar system inherited by the Mayans must understand the above phenomenon and find a way to skillfully combine it with other related cycles. In addition, by combining these cycles for mathematical calculation, the ancient calendar masters clearly know that 584 days is only an approximate value, and that the movement of Venus is not very regular. Therefore, they calculated the exact average of the rendezvous period of Venus in a long period (which has been confirmed by modern science), that is, 583.92 days. This number has been incorporated into the Mayan calendar in countless extremely complicated and incomprehensible ways. For example, in order to make it coincide with the so-called "holy year" (260 days, divided into 13 months), historians stubbornly revised it every 6 1 Venus year by 4 days. In addition, every five such cycles should be revised for another 8 days at the end of the 57th rendezvous cycle. The division of Mayan calendar combines the sacred year with the rendezvous period of Venus so closely that the error produced by this equation is surprisingly small, only one day every 6000 years. What is even more admirable is that the Mayan calendar masters also have a set of carefully calculated adjustment schemes, which make the Venus cycle not only coordinated with the "holy year", but also have a just right relationship with the solar year. The purpose of this painstaking effort is to ensure that their calendars can be accurate for a long time. Does this "semi-civilized" Mayan tribe need such a high precision calendar? Or did they just inherit a set of calendars that worked well and were suitable for older and more advanced civilizations? The jewel in the crown of Mayan calendar is the so-called "long calculation". This system for calculating the date also expresses the belief in the past history: the famous concept of great cycle, which was widely believed by the Mayans. They think that time runs in a big cycle. These cycles are from the creation to the destruction of the world. According to the Mayans, the current great cycle began in 4-8 BC. This day is equivalent to 311August 4 13 on our calendar. They also believe that on the day of 4 Ahua 8 Kankin, that is, our 201212 February 23rd, in a global devastating disaster, this cycle will go to extinction. The function of "long calculation" is to record the passage of time since the beginning of this great cycle. To be precise, it is to deduct the 5 125 years allocated to today's mankind year by year. In Maya's mathematical chart, the route of time travel extends so far into the past that the human brain can't imagine and understand it at all. But the Mayans pursued the beginning of time along this route without hesitation. Every step forward will open up a new situation. Centuries add up to thousands of years and thousands of years add up to thousands of years. In this way, these tireless explorers step by step into the endless past. A stone tablet unearthed from the site of Girigua in Guatemala bears the date they calculated 90 million years ago, and another stone tablet records the date 300 million years before that. They are all calculated step by step, and the month and date are clear, just as we calculate the past Easter arrival month according to our calendar at the same distance. This astronomical figure is really dazzling ... is it too avant-garde for a civilization that is lacking in many aspects? Mayan architecture itself is not bad, but other than that, nothing can prove that these Indians living in the jungle have (or need) the ability to imagine for so long. Most western intellectuals gave up the view that Bishop Heuchel's world was created in 4004 BC, and they finally admitted that the age of this world was unknown, which only passed more than one hundred years. To put it bluntly, before Darwin put forward the theory of evolution, the ancient Mayans knew more accurately how old our planet was and how long the geological time was actually than the British, Europeans and North Americans. The question is: How did the Mayans calculate hundreds of millions of years so freely? Is it an abnormal phenomenon of cultural development, or did they inherit those calendars and mathematical tools, which promoted and helped them develop this complex operation? If we really inherit any legacy, we naturally want to know the purpose of the people who invented this computer-like Mayan calendar. What do they want to do with it? Really, as an authority said, to conceive such a complicated and sophisticated thing is just "a challenge to intelligence, just like playing crossword puzzles"? Do they have more practical and important goals in mind? We can see that what Maya society is most obsessed with, and actually what all ancient peoples in Central America are most concerned about, is to calculate the time of the end of the world. If possible, try to postpone its arrival. Could this be the expected task of this mysterious calendar? Could it be a machine that predicted some terrible cosmic or geological disaster? Through these findings, we can only speculate that the Mayan civilization was once a powerful high-tech family, or the successor of the high-tech family, so these things are uncertain.
