The sad part of our human existence is that none of us ever live to see how our story ends. We "spawn" at a random point in time and "vanish" at another. Ageing is being worked on vigorously and while we did change our lifespan from 40 years to 80 years of existence thanks to modern science, in order for us to truly comprehend changes on a universal scale, average human lifespan would need to be 50000 years long. That way you'll see species evolve, continents move, quasars explode, maybe even Betelguese explode?
