" If God does not exist, life can be considered absurd. If there is no God, man is inevitably doomed to death. like all biological organisms, he must die, and with no hope of immortality, his life leads no further than the grave."
" It might be said that his life held importance because it influenced others or affected the course of history. But this gives only a relative significance to his life, not an ultimate significance. His life may be important relative to other people or certain events, but those people and events are insignificant, since they too are headed foe non existence. All of history and it's events and persons are meaningless, so what ultimate significance is there in influencing any of them ? :"
The universe will die, as will all humanity and no matter how long they exist, they can inhabit only a tiny flash of time in eternity.
The problem of man; because he and everything end in nothing, he and everything are nothing, and can have no value, no importance, no ultimate significance. Man and everything are absurdities Quotations from, The Existence of God and the Beginning of the Universe. By William L. Craig, PhD., D. Theo.
THOUGHTS ?
In the short term of human (or any other living thing) lifespan, life is what you make of it, it has meaning to yourself and those close to you. You may leave a legacy in some way that has meaning to future generations
Longer term, nope, nothing other than a convenient store for a small amount of matter and energy. Which will literally return to earth and becomne paert of its structure.
Longer still, part of that matter and energy may become vital to another life (in this way we are all made of dead people).
And longer still, part of you may become rock to some newly formed planet or help power a sun shining on some future civilisation. A process that will continue as long as this universe lasts.
That's meaning enough for me.
