“Sometimes, question is raised that what is the purpose of the universe and other species. Why there was a wait for billions of years before humans began to exist in the universe. What is the purpose of millions of other life-forms in animals and plants? Why there is no life on other planets?

First of all, time is a relative concept. Thus, human’s conception of time on planet earth is just how we experience movement of earth around sun and about its own axis. Venus and Mercury take longer time to fully rotate about their axis than to complete their orbits around sun. This means Venus and Mercury have days that last longer than their years, i.e. orbiting around sun is faster which determines years and rotation around their axis is slower which determines days.”
