When it comes to life we, as human beings, have a unique perspective. We, to our knowledge, are the only self conceiving creature in the sense that we can think beyond our own physical need and reaction. We can actually think about ourselves, our past experiences, our future plans and our existence. How to put a value on this ability to conceive a higher thought? It would seem to be priceless. It does however have draw backs in being able to conceive sorrow and sadness so perhaps our value does not lie there.
Perhaps our existence has a certain value in the grand scheme of all things. Perhaps our human existence has or will improve the universe; indeed being the highest life-form on our planet and it being the only planet that we know of able to sustain life certainly puts us in a unique circumstance. A “one of a kind” usually has a value measurable only in the eye of the beholder. Then the definition of value has to be defined by who’s asking (a priceless unique vase or coin has little value to one who is starving, while a collector may pay millions and scoff at a dried out dinner roll and half-eaten salad.)
Then who is to define our value; Perhaps God? A unique creation with a mind of it’s own to conceive things that the creator had not conceived on his own and to have the free will to choose our own thoughts. Who can put a value on one’s child?
Perhaps we can put a value on ourselves! Some people put very little value on human lives (Think Hitler, think of the terrorism of our time and the hatred towards our fellow man.) Yet, can anyone put a value on an emotion, on watching a sunset or smelling the aroma of a much anticipated meal, the touch of another human, listening to a favorite song, the pride of succeeding?

There are so many things that we cannot fathom when it comes to our own existence, yet when taking into account those things that we can it would seem obvious that our life as humans is priceless!
