Everything changes ; that’s dialectics. Nothing stays the same forever . There is no rock of ages ; even the Sun will burn out one day ( a billion years or something) . Everything has a beginning -middle - and end. Like plays. Or lifetimes. There are no immortal beings . There is nothing but matter, and motion is its mode of existence ; motion is change . The only way we know there is time is because there is change ; change is the sign of time . Natural historical science of evolution is science of change . There is but one science - the science of history; history is change , natural evolutionary change and human evolutionary change over many generations. Some species have come to an end over the millions of years of Life on Earth. 🌍
