Human beings have virtually no value if they are just machines

[Chad32]

Only having one finite existence makes something more valuable. Not less. Value is dictated by rarity, after all. Yes some things have more value than others, like your one mother over a replaceable shaver. What value to we gain from having an eternal existence. I'd argue that this life means nothing, if we're going to become eternal spirits after this. Life is short, therefor it has value. If you live for eighty years on this world, what difference will is make eighty thousand years from now when you're in the next life?

The thing that you think gives us value, I argue takes away from it. Because something that lasts forever isn't valuable. Something being finite and rare is what gives it value.

The thing is, the average human lifespan is nowhere near enough time for me.  As long as I am happy, having fun, and enjoying my life, then I would want to live like that for perhaps trillions of years or maybe even forever.  But as long as I have to live a life of depression, misery, and unhappiness, then that is no way to live for me and it is a life of no value.  The fact of the matter is, if I grew tired of living a happy and fun life after 60 or so years, then I would find much value and worth in this life being finite.  But I don't grow tired of a happy, fun life and the fact that this life isn't a happy life that lasts for perhaps trillions of years means that it isn't as valuable of a life to me.

One problem with infinity is, you will eventually do everything that anyone could ever think of doing, more times than you can count. And while 80+ years may not be enough for you, that's all the more reason to live life to the fullest. That doesn't make life lose its value. It makes every second even more valuable.
