Why do people have to be this lonely? What's the point of it all? Millions of people in this world, all of them yearning, looking to others to satisfy them, yet isolating themselves. Why? Was the earth put here just to nourish human loneliness?

This quote is asking why people are feeling so alone in the world. It is suggesting that even though there are millions of people in the world, they are all looking to other people to make them feel satisfied, but they are also choosing to isolate themselves from one another. The quote implies that there may not be a reason for the loneliness experienced by human beings – it could be something that is just part of life. The question being asked is why the Earth was created if it just causes people to feel lonely.
