There is only one of every species, by definition of species. You can have a number of varieties within one species, and Homo sapiens is no exception. We just don't call distinct human groups a "variety" even though there are obvious differences between sub-groups.

One definition of species is that they can't interbreed with fertile offspring.
But in many cases, they are distinct because they live too far apart.
It seems that lions and tigers can interbreed, but normally live too far apart.
The offspring, ligers and tigrons, depending on which one is the mom and which is the dad. But humans have spread all over the world.
Otherwise, we have carefully defined species such that there is only one of us!
