no one knows for sure, best guesses I've read puts it at about 110 billion. again this is the number of people who have ever lived. the number of people alive today is close to 7 billion. i only mention this because the previous answer to this question was 6.7 billion.
It is impossible with our present knowledge to get an accurate answer. We just don't know enough about the origin of homo sapiens as well as the the average life spans of our ancestors. Unless you are a creationist you know that humans are the latest evolution in many species from the ape branch. Some say the species we call humanity spawned about 2 million years ago although archaeologists are still finding bones of our fore fathers dating back even further.
If you class humans as people living in society then the estimate is about 60 billion. If you want to believe that the nomadic people that roamed the African tundra throwing spears at mammoths and arguing with neanderthals are the same as us genetically, then the estimate is about 110 billion.
It is estimated that around 108 billion people have ever lived on Earth since the beginning of human history. This estimate is based on various demographic studies and historical data.
