Because we live in a society and are social animals. The only way to achieve something big is by cooperating with other people. Big groups of people working together are able to achieve amazing things. Individuals cannot even really built a modern house,by themselves. It is a collective societal effort that allows for modern homes to be constructed( for example).
Come to think of it, I doubt I could even build a mud house on my own. Even the individual bricks needed to build a completely bare bones "house" are also a huge collective effort of humanity.

A good way of looking at it is that it fucking sucks to do hard or complicated shit by yourself.
