The believer in God has to account for one thing, the existence of unjust suffering; the atheist, however, has to account for the existence of everything else.

paraphrasing Milton Steinberg in a debate (2008) with Christopher Hitchens and Dinesh D'Souza. A slightly different version ('must' twice instead of 'has to' and 'evil' instead of 'unjust suffering') is found in Dennis Prager and Joseph Telushkin, The Nine Questions People ask about Judaism (1981), Question 1.
