Agnotic- n- a person who holds that whether God exists is not known and probably cannot be known.
Religion does not hold a monopoly on morals. There are many people that give to charity, volunteer to help the less fortunate, live an honorable life, love their families, respect others, and generally contribute great things to society. All without the need to believe that they will be rewarded for their good deeds, or punished for their transgressions; by some deity in the afterlife.
