What is we never asked?

According to world population studies, approximately 108 billion people have lived on this planet. Assuming that the average lifespan of all these people was 25, there has been around 2.7 trillion years of life, if we multiply this by the number of days in a year (365), there is a total of 985,500,000,000,000 days of life (985.5 trillion days). Not once in any of those days did anybody ask.
