Although you may not stumble across a Martian in the garden, you might stumble across yourself. The day that happens, you'll probably also scream a little. And that'll be perfectly all right, because it's not every day you realize you're a living planet dweller on a little island in the universe.
Imagine that one day you are out for a walk in the woods. Suddenly you see a small spaceship on the path in front of you. A tiny Martian climbs out the spaceship and stands on the ground looking up at you… What would you think? Never mind, it’s not important. But have you ever given any thought to the fact that you are a Martian yourself? It is obviously unlikely that you will ever stumble upon a creature from another planet. We do not even know that there is life on other planets. But you might stumble upon yourself one day. You might suddenly stop short and see yourself in a completely new light. On just such a walk in the woods. I am an extraordinary being, you think. I am a mysterious creature. You feel as if you are waking from an enchanted slumber. Who am I? you ask. You know that you are stumbling around on a planet in the universe. But what is the universe? If you discover yourself in this manner you will have discovered something as mysterious as the Martian we just mentioned. You will not only have seen a being from outer space. You will feel deep down that you are yourself an extraordinary being.
If we wish to draw philosophical conclusions about our own existence, our significance, and the significance of the universe itself, our conclusions should be based on empirical knowledge. A truly open mind means forcing our imaginations to conform to the evidence of reality, and not vice versa, whether or not we like the implications.
Do you see the slightest evidence anywhere in the universe that creation came to an end with the birth of man? Do you see the slightest evidence anywhere out there that man was the climax toward which creation had been straining from the beginning? ...Very far from it. The universe went on as before, the planet went on as before. Man's appearance caused no more stir than the appearance of jellyfish.
When you are lonely for a while don't get restless, if you had born alone, you are going to die alone then for sometime you can certainly live alone.
