There is an opinion, common among scientists and intellectuals, that our Earthly existence is not only rather ordinary, but in fact, insignificant and purposeless. The late astronomer Carl Sagan typifies this view in his book "Pale Blue Dot":
Because of the reflection of sunlight the Earth seems to be sitting in a beam of light, as if there were some special significance to this small world. But it’s just an accident of geometry and optics.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
