Actually, assuming the average height throughout history is around 5.53 (Homo Erectus- Homo Sapiens)
And that 107 x 10^9 is the approximate total human population, then we would span approximately 1.7655868210611e-5 ly when stacked on top of each other vertically. Otherwise if the current Human population were to assume this form, then we would be 1.438022998269e-6 ly. In short, no you are wrong.
