I dont think you need religion or God to know right from wrong, because the law of the land is based on the same premise.

Thou shalt not steal...Steal and you go to Jail
Thou shalt not kill...Kill and you go to Jail

and people can be good people and be atheists, I know several who laugh at the idea of going to church and they are basicly good people.

It's instinctive to be good to people, our parents teach us dont be rude, dont walk away from that person, shake their hand etc, they usually dont say "god wants you to be nice" they just say "be nice"

It's just basic living.

If you kiss peoples ass, usually you get your ass kissed back.
If you are a jerk to people you will be treated like a jerk.

It's just how we interact.

To me religion and spirituality is something that teaches about later on down the road.
