Polite English slogan

A small step forward is a big step for civilization. One small step ahead, one big step civilization. This should be the slogan of the men's room. Our group suggests translating it in this way, imitating the famous saying of landing on the moon: this is a small step for mankind, but a big step for mankind. This is one small step for man and one giant leap for mankind. Civilization = civilized society, human civilization = civilized behavior, courtesy We think the word "civilization" in this sentence is more appropriate to be translated as civililty. Translation is an art, not a science. There is no uniform answer, so we can only choose the best translation. I hope the landlord will consider the reasons put forward by the group and choose the answers recommended by the group. Next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can = next to trash can. If we really don't just say "civilized behavior", but want to rise to the height of "human civilization", we can change it to: a small step ahead, a big step for civilization.
