I have read that an estimated 110 billion people have lived on earth since the first humans appeared.
The population that are alive with today on earth is about 8 billion people. Perhaps around 7% of all the people who have ever been born on earth since the beginning, are living today. All the others died physically, as we all will.
Where are those who are perhaps 100 billion dead who lived before us? Where are they? Where did they go?
