Ok....I say Arabs for the numbering system
Don't you mean India then? It's known as Arabic numerals because that's who Europeans learnt them from.
I would say Greece/Rome. As bjohnson says, Ancient Greece has had the greatest influence on European/Western culture, especially after the Renaisance. India and China would be the other big hitters I guess.
It sepends what you mean by science/culture though of course. If you are talking technology, then you could argue the UK as the founder of the industrial revolution, or the US for the innovations that have come from the cold war and space race, or Japan in more recent times.
All cultures and countries have had an influence upon the world and it depends what aspect of life/culture/science etc. you are considering and what you consider the important elements, and where you are considering them from.
