Ending of Humans.

One question will come in everyone's  mind is that Is there any end in humans life?

So the short answer is Yes.

Genetic bottleneck in humans

According to the genetic bottleneck theory, between 50,000 and 100,000 years ago, human populations sharply decreased to 3,000–10,000 surviving individuals.

Humanity has a 95% probability of being extinct(end) in 7,800,000 years, according to J. Richard Gott's formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.
