The zero has been around for a long time. It was independently discovered by the Mayans using a base twenty system. What has not been around has been a convenient system for doing arithmetic on paper or blackboard that made effective use of the zero and base ten in the first place.
That would be nice to ferret out.

Year Zero: Ancient Indian Text Includes Oldest Recorded Zero Symbol

Scientists
claim to have traced the earliest example of one of the most
significant conceptual breakthroughs in arithmetic to an ancient Indian
text, known as the Bakhshali manuscript. The specific manuscript has
been housed in one of the Bodleian Libraries at the University of Oxford
since the very early days of the 20th century.
Oldest Zero Symbol Discovered?
As the Guardian reports, radiocarbon dating divulged the fragmentary text, which is engraved on seventy pieces of birch bark and contains hundreds of zeroes, dating back to as early as the third or fourth century. This makes it the world’s oldest known origin of the zero symbol that we use in the modern world, as it is about five centuries older than experts previously thought. Marcus du Sautoy, professor of mathematics at the University of Oxford, tells Guardian, “Today we take it for granted that the concept of zero is used across the globe and our whole digital world is based on nothing or something. But there was a moment when there wasn’t this number.”

During the latest research, three samples were extracted from the
specific manuscript and examined at the Oxford Radiocarbon Accelerator
Unit. The results showed that the three samples come from three
different centuries, one from 224-383 AD, another from 680-779 AD and
another from 885-993 AD, making experts curious about how the manuscript
ended up being a single document.
According to Richard Ovenden, head of the Bodleian Library, the results of the study clearly show how the contributions of South Asian scholars have been traditionally ignored in the Western world, “These surprising research results testify to the subcontinent’s rich and longstanding scientific tradition,” he told Guardian.
The Bakhshali Manuscript
The manuscript was discovered in 1881 by a peasant in the village of Bakhshali, which is near Peshawar, now in Pakistan. The extant manuscript is incomplete, consisting of seventy leaves of birch bark. The intended order of the seventy leaves is indeterminate. In 1902, the Bakhshali Manuscript was transferred to the Bodleian Library, Oxford, where it is still kept, but experts suggest that it is too fragile to be examined by scholars.

In the fragile document, zero does not appear to be an individual
number, but instead it seems to be a placeholder in a number system,
just as the “0” in “101” indicates no tens. It features a problem to
which the answer is zero, but here the answer is left blank.
The Historical Significance of Zero
Many ancient cultures came up individual with similar placeholder symbols throughout history. Ancient Egyptian numerals were base 10. They used hieroglyphs for the digits and were not positional. By 1770 BC, the Egyptians had a symbol for zero in accounting texts. By the middle of the second millennium BC, the Babylonian mathematics had a sophisticated sexagesimal positional numeral system. The lack of a positional value (or zero) was indicated by a space between sexagesimal numerals.
By 300 BC, a punctuation symbol (two slanted wedges) was co-opted as a placeholder in the same Babylonian system. In a tablet unearthed at Kish (dating from about 700 BC), the scribe Bêl-bân-aplu wrote his zeros with three hooks, rather than two slanted wedges. However, the Babylonian placeholder was not a true zero because it was not used alone. Nor was it used at the end of a number. Thus numbers like 2 and 120 (2×60), 3 and 180 (3×60), 4 and 240 (4×60), looked the same because the larger numbers lacked a final sexagesimal placeholder. Only context could differentiate them.

Eventually, it was the dot symbol in the Bakhshali script that
evolved into the hollow-centered version of the symbol that we use
today. It is also seen as the progenitor of zero number that we first
meet in a text called Brahmasphutasiddhanta, written by the Indian
astronomer and mathematician Brahmagupta in 628 AD. “This becomes the
birth of the concept of zero in its own right and this is a total
revolution that happens out of India,” Du Sautoy tells Guardian.
And adds, “This is coming out of a culture that is quite happy to
conceive of the void, to conceive of the infinite. That is exciting to
recognize, that culture is important in making big mathematical
breakthroughs.”
The manuscript will be on public display on 4 October, as part of a major exhibition, Illuminating India: 5000 Years of Science and Innovation, at the Science Museum in London.
