Life expectancy is the expected (in the statistical sense) number of years of life remaining at a given age. It is denoted by ex, which means the average number of subsequent years of life for someone now aged x, according to a particular mortality experience. (In technical literature, this symbol means the average number of complete years of life remaining, excluding fractions of a year

It is denoted by ex, which means the average number of subsequent years of life for someone now aged x, according to a particular mortality experience. (In technical literature, this symbol means the average number of complete years of life remaining, excluding fractions of a year. The corresponding statistic including fractions of a year, the normal meaning of life expectancy, has a symbol with a small circle over the e.) Because life expectancy is an average, a particular person may well die many years before or many years after their "expected" survival. The term "maximum life span" has a quite different meaning. The "median life span" is also a different concept although fairly similar to life expectancy numerically in most developed countries.

If your looking for a meaning of life, it's hard to actually say WHAT it means. Life is labor. Life is joy. Life is sadness. Life is harsh. Life is. Well, that's NOT science. For science, it's the while we have on earth. If you mean "Did the world have life before us?" That is a yes and no question. The dinosaurs were wiped out and the Ice Age melted. But there was life.....
