Even a life of no religion(being a soft or hard atheist) seems to still be a religion. All they do is subsitute something else for God(money,sex,material things, their own vain desires), these things become their God.They perform rituals daily worshiping their false God. What do people call out when having sex..ohhh God its good, or how about if they find $100,000, oh my god look at this!! We are all guilty of it but if we are to look at the religion of God which is to take no other God for worship except Him. We find that those who dont believe in God or religion have already replaced God with their own personal god or gods and they go through rituals worshiping those gods.
