How does the Book of Changes explain what the universe is and its origin?

The Book of Changes, like Buddhism, is a general explanation of everything in the world. According to the Book of Changes, infinity gives birth to Tai Chi, Tai Chi gives birth to two instruments, two instruments give birth to four images, and four images give birth to eight diagrams and eight hundred and sixty-four hexagrams. Buddhism says that there are three thousand worlds, and the wheel of karma has six divisions. These things can't be compared with modern astronomical discoveries and celestial science research at all. I ching only talks about general philosophy and dialectics, not about the specific universe. Buddhism despises life, advocates cultivation, and returns to its roots for perfection. It seems that their eyes see the truth of the universe, and they can't describe it correctly to human beings. It's just called enlightenment What is profound? But a heresy that modern people can't understand and use. It can be said that I ching didn't explain the universe at all, because the ancients couldn't see what the universe was. We don't see anything profound about the I Ching. What really explains the universe is the big bang theory now.
