All Alone

I don't think that we are meant to be alone. It's not natural. It's frightening. When you think about it on an natural, evolutionary basis, we are social creatures. We live in groups to survive. We are not as big or strong, or as fast as some of the other predators in the natural world. Our ancient ancestors lived in groups to help insure survival. Together they were able to fend off large threats and keep each other safe. These primitive traits learned to carry on to our currents lives and is why we seek comforts from others. We are all familiar with that old saying, strength in numbers. It also applies to our mental happiness. We need other people with to give us comfort, strength, and hope. Things that, in a dire time, we can not give ourselves.  And so we turn to others. Being alone, is more of a punishment than it is a gift.

Now we may be able to gather our thoughts when we are by ourselves. We are able to think clearer and process things better when we're alone, maybe. But who will challenge these thoughts, how will we know if we are right. After awhile our thoughts are no longer enough. They do not sustain us like a real person can, that is why we start making people up. 

In the movie "Into the Wild" we witness Chris McCandless come to this realization unfortunately late in his life. He realized that he was happy when was with others. And this was actually pretty evident through the movie. Now, is that actually true for his real life, I can not say, but it might hold some truth. If he did spend time with generally good people he would have been happier with them then alone.
We are not supposed to be alone. We need others to share our thoughts and useless information that is racing around our minds. Without this means of an export, we go crazy.
