My fans, do you like history? Did you especially pay attention in class when you were still going to school? Now that we are adults, we have a certain level of interest in things related to history, because we can learn a lot of knowledge from it. I heard that Earth has 4.6 billion years of history, and living things have 3.8 billion years of history. After so long, humans have evolved to this modern time. With so much time having passed, I think there must be other highly intelligent creatures existing that humans don't quite understand. Do you agree?
