Can it be calculated with a very good degree of accuracy, "How many people are born on this earth from the start of our human civilization, including the existing population of earth?" Would you kindly find it for me with your rational estimations?

yeah, it can be calculated with accuracy, probly within 2% of the actual number i heard once something like all the people who lived up till now equals the ones alive today I'm gonna guess 20 billion people total on Earth for all time it doesn't matter that much when you say our ancestors were people, so few then 3 million years ago or 1 million wouldn't matter much
