However, I do not believe it is necessary to hold any kind of religious belief in a divine being or being(s) in order to be moral or good. Humans have been around way longer than most modern religion and have managed to survive.
You don’t have to believe in deities but you can believe in causes or people.
There are people out there who believe in giving, taking care of the poor, healing the sick, saving the environment, championing civil rights, sheltering the homeless, finding cures for diseases, developing new scientist instruments/methods to help humanity and so on. Likewise there are people out there who believe in money, or themselves, power, fame, riches, etc. None of these require the belief in a deity(ies)…that’s not to say that the two are mutually exclusive.
