![“[ 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)
![“I don't like being away from home. That's one reason why I don't work as much as I used to [when I started my career], because so many things are on the road. I just don't want to be away from my husband, my dogs and my home. I don't sing that much any more because that also takes you on the road.” quote by Jane Powell](https://sms4smile.com/quotes/img-quotes/07c/jane-powell-36243_away_i-don-t-like-being-away-from-home-that-s_278.jpg)
