Astronomy Quote by Carl Sagan
““The Cosmos extends, for all practical purposes, forever. After a brief and sedentary hiatus we are resuming our ancient nomadic way of life. Our remote descendants, safely arrayed on many worlds though through the Solar System and beyond, will be unified by their common heritage, by their regard for their home planet, and by knowledge that, whatever other life may be, the only humans in all the Universe come from Earth.””

![“[ When a religious couple wrote to Sagan about fulfilled prophecies, he wrote back in May 1996 :] If ‘fulfilled prophecy’ is your criterion, why do you not believe in materialistic science, which has an unparalleled record of fulfilled prophecy? Consider, for example, eclipses.” quote by Carl Sagan](https://sms4smile.com/quotes/img-quotes/875/carl-sagan-160_belief_when-a-religious-couple-wrote-to-sagan-a_25095.jpg)
