I don’t know how one would have a positional numeral notation without zero, even if it’s denoted by an empty space. Sure enough, reportedly the symbol for zero appeared in the Hindu numerals, derived from the non-positional Brahmi system. Although apparently both ancient Babylon and China already had their own positional notations, both with a space for zero.
didn’t Arabs also introduce zero?

Arabs added a system for fractions instead.
