Apparently, the figure is guesstimated at around 106,456,367,669 - since 50,000BC!

RESiNATE Reviewed by RESiNATE on . Insomnia I've got insomnia :( I wonder how many people have actually walked this Earth, since time began... If there are 6.5Billion people on this planet now, and a person is born every 2 seconds, and someone dies at the same time, it shouldn't be too hard to figure out...should it? How long has this planet been habitable? Multiply that by 6.5Billion, and the answer should be something around that figure, yeah? But, of course there hasn't always been 6.5Billion people alive at any one time, Rating: 5
