Take care of the earth!

One day in the year 50,000, more than two dozen archaeologists from the Milky Way, Orion, Cepheus and the Solar system W gathered at an ancient ruin on Earth at the invitation of the Institute of Paleontology at the Center of the Cosmos. Through the archaeological excavation of the ruins of the Earth, we want to find and discover the reason for the extinction of the paleontology that has existed on the earth for nearly 100 million years.

A few days later, the discovery of an intelligent robot dog reveals signs that 10,000 years ago, the earth was ruled by a superior animal called man. At that time, the earth people had already had the primary civilization. It can be seen from the reports of each group of discoveries that the people at that time had preliminarily mastered the technology of entering space and knew how to use some plant fibers to weave something called cloth to block the attack of climate on the human body. Know how to synthesize food with fat and starch of some animals and plants; Know how to make some low-level vehicles for hailing cars, boats and planes; Know how to write down their history. However, the form is extremely simple, mostly in a thing called "paper" records. The writing is very irregular, some like low-level caterpillars, some like squares, some like a pile of slightly arranged roots. Unable to decipher, the only way to get a more convincing answer is to wait for team C to send it to the space Language deciphering room at the center of the universe. Perhaps it will also shed light on the real reason why this advanced animal became extinct on earth. Help further unravel the cosmic mystery of our demise.

After another stage of separate excavation, the archaeological groups again made many important discoveries. Team B found "uranium" and some nuclear waste from the ruins of a desert used to make suicide weapons. Evidence of the use of such weapons was found in several areas. Team D found large amounts of deadly chemicals in the soil and water from the ruins of several cities. And tested a variety of deadly toxins from fossilized human bones. Team C found traces of a submerged city at the bottom of a dry lake, and there were signs that this was a bustling city that had been submerged almost overnight. A stratigraphic survey of the surrounding environment revealed that about 200 kilometers of the city were barren hills, with virtually no vegetation during the flood. After excavations and various investigations, team A found that about 10,000 years ago, the once prosperous earth almost lost all resources available to human beings. Serious environmental pollution, harsh weather conditions, are likely to make this advanced animal human sudden extinction. There seemed to be no need to waste any more time digging, and the teams left the dry, desert, lifeless earth with their findings to report back to the center of the universe.

In a conference hall in the center of the Universe, N expert leader listened to the report of each archaeological group, combined with the decoding of human written records of the information, all kinds of information through telepathic feedback to the intelligent information processing center. After a while, it came to the conclusion that the extinction of mankind on earth was caused entirely by man's own destruction of the ecological balance, pollution of the living environment, squandering of natural resources, endless wars, and the failure to find a second habitable planet. In a word, man destroyed himself.

Therefore, the earth is our big family for everyone to survive, for the future of mankind, we must take good care of the earth, take good care of our home!
