Perhaps humans are just genetically setup to spend time talking to each other.
Over hundreds of thousands of years, those of our ancestors who got together under a deep purple African sky, lit by trillions of stars, gathered around the glowing embers of the fire, picking the last bits of meat from their antelope, were better able to hunt, survive and reproduce.
The groups that tried to get by in dumb animal silence ended up being out-competed and vanished.
So now, in our modern 21st century world, where opportunities for hunting wild animals in groups out on the savannah are a bit limited, our brains still crave the same experience, and so keep coming back to this ersatz version of that ancient ritual.
