is there meaning to life?

Carl Sagan was an atheist and he shared an amazing love for his wife Ann Druyan. When he died she wrote, "I don't think I'll ever see Carl again. But I saw him. We saw each other. We found each other in the cosmos, and that was wonderful.” Such love is real & admirable. But can love, beauty, and purpose truly mean anything if we are nothing more than "star stuff"?
