Well that depends. With customary animated aplomb, German educational design studio Kurzgesagt sez:

The observable universe is a big place that has been around for more than 13 billion years. Up to two trillion galaxies made up of  something like 20,000 billion billion stars surround our home galaxy. In the milky way alone scientists assume there are some 40 billion earth like planets in the habitable zone of their stars. When we look at these numbers it is hard to imagine  that there is nobody else out there.

A sobering reflection on life, the Universe and everything from the always fascinating German education design studio, Kurzgesagt. To wit:

Picture  yourself as a slinky falling down an escalator moving upwards – the falling part represents the self replicating processes of your cells, the escalator represents  the laws of physics, driving you forwards. To be alive is to be in motion but never arriving anywhere. If you reach the top of the escalator there is no more falling possible and you are dead forever.
