If all life-forms including celestial bodies are evolved out of interstellar gases and dust do we have a specific centre? Every element in our body has been a wanderer among clouds of interstellar gas, and having come together by some sort of an arrangement should we not have been equally at home in cosmos as well?
To all intents and purpose we consider the earth as our home and millennia of living here has shut out much of our cosmic ancestry; and in compensation we have acquired an ability to live on the earth. This truth is brought home when we try to travel in space.
