The first evidence we have of zero is from the Sumerian culture in Mesopotamia, some 5,000 years ago. There, a slanted double wedge was inserted between cuneiform symbols for numbers, written positionally, to indicate the absence of a number in a place (as we would write 102, the '0' indicating no digit in the tens column).

TIMELINE shows the development of zero throughout the world. The first recorded zero appeared in Mesopotamia around 3 B.C. The Mayans invented it independently circa 4 A.D. It was later devised in India in the mid-fifth century, spread to Cambodia near the end of the seventh century, and into China and the Islamic countries at the end of the eighth. Zero reached western Europe in the 12th century.
Writing Numbers
The Babylonians displayed zero with two angled wedges (middle).
The Mayans used an eyelike character [top left] to denote zero.
The Chinese started writing the open circle we now use for zero.
The Hindus depicted zero as a dot.
The symbol changed over time as positional notation (for which zero was crucial), made its way to the Babylonian empire and from there to India, via the Greeks (in whose own culture zero made a late and only occasional appearance; the Romans had no trace of it at all). Arab merchants brought the zero they found in India to the West. After many adventures and much opposition, the symbol we use was accepted and the concept flourished, as zero took on much more than a positional meaning. Since then, it has played avital role in mathematizing the world.
建议去微博看下墨者几何的文章，他把我们老祖宗的科学书籍都翻出来了，原因很简单，鸦片战争之前他们根本没有完整的科学体系，就是鸦片战争之后到中国抢来的
西方偷学中国技术，在这基础上进行改善
近现代科学诞生于欧洲，这是不争的事实。那些非要说欧洲偷了永乐大典的，请告诉我永乐大典那一章那一卷提到过微积分。
西方所谓的科学大拿发明、发现了各种定理全是中国古书上的
