Quote by Carl Sagan

"Somewhere, something incredible is waiting to be known."

"The cosmos is a vast living body, of which we are still parts."

"Science is a way of thinking much more than it is a body of knowledge."

"For small creatures such as we, the vastness is bearable only through love."

"Gratitude makes life richer."

"A grateful heart is a happy heart."

"Respect those who came before us."

"Life's greatest treasures are the people we love"
