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.

In a new episode of the PBS animated Blank On Blank series, the astronomer Carl Sagan talks to Studs Terkel in 1985 about his concerns that humankind didn’t havw the ability to communicate with extraterrestrial life. To wit:

Look at timescales, you realize that our civilization is the most backward civilization in the galaxy that could communicate at all, because we’ve just invented radio telescopes,just a few decades ago. We had not the ghost of a chance of communicating with anybody else.So If we receive a message, it can’t be from anybody less capable than we, because anybody less capable can’t communicate at all. So it has to be somebody much in advance of us and maybe as much in advance of us as we are in advance of the ants, say, or the worms.
