I haven't read any geologic books in English. I could get some geologic words. However, Jan Zalasiewics explains some geologic knowledge. Our human beings' history is much shorter than the long histroy of the Earth. After one hundred million years, some species may find some remains. We could meet aliens before elimination of human being on the Drake equation.L is the length of time such civilizations release detectable signals into space.
