I Can See Your HP

Why are humans, as creatures of the earth, so easily destroyed by nature? Why is there a non-existent creature among the twelve zodiac signs? Why are there such close plots in Chinese and Western mythological stories when it is difficult to connect with each other? Do the various rare and exotic animals, mountains and rivers in the Classic of Mountains and Seas really exist? Floods flooded the world in the west, and Dayu controlled the floods in the east. Is there some indescribable connection between all these? ------------------------------------------------------------------ Think about it from another angle~ What if... Maybe we humans have never been the native life forms of the earth?
