How much space would the human race occupy if they stood all together?

If the entire human population, estimated at around 8 billion people, stood closely together, they would occupy approximately 0.5 to 1 square meter per person. This means they would require around 4 to 8 million square meters of space, equivalent to about 1,000 to 2,000 acres. To visualize, this area could fit within a small city or several large parks. However, the actual arrangement and density would affect the total space required.
