That question is crazy-hard to answer. Not only are we unsure about when Homo sapiens first appeared, but we are also unsure about prehistoric populations and growth rates.
Nevertheless Carl Haub at the Population Reference Bureau has attempted to "guesstimate" the figure. Using known population data to devise artificial growth rates for prehistoric populations, and with a starting date of 50,000 years ago, Haub has calculated that there have been perhaps 106 billion humans on Earth ever since the whole H. sapiens thing first started. It's a horrible, rough estimate, but pretty interesting.

One. Everyone else, it turns out, was a figment of Réné Descartes' imagination.
