“Convince” yourself? If it just is that way it requires no convincing.
That’s the whole point - meaninglessness is only ‘the way it is’ if you refuse to engage with the experience of being alive.
And hunger pangs telling you you’d like to eat don’t somehow give eating a real meaning if the life youmare sustaing by so doing has no real value.
Does your life have no value to you? Do you only enjoy it because you are convinced it will last forever?
Also, the concept of “gratitude” is silly in this context. Who are you grateful to, the uncaring universe?
Gratitude does not require a personal object, just as sorrow and regret do not require feelings of personal guilt. Approaching life with a sense of gratitude - to the impersonal universe, if you must have an object - entails an appreciation of just how improbable it is that you, as an individual person, exist at all. Perhaps this is a glass-half-full philosophy, but it works for me. Why should I allow my days to be consumed with regret for all the things I’m not, rather than wonder at all the things I am?
And for what, the luck of having a possibly less terrible temporal experience than another, though the same meaninglessness hold over all and await all in the end? Absurd.
Only absurd if you ignore the experience of the moment. If you believe this life to be important in and of itself, because it’s the only one we get, the motivation to make life better for all with whom you interact is far more compelling than the feeling that you can just leave it to eternity to decide the fate of your fellows.
You are flailing because the obvious truth is there to see: atheism IS nihilism, logic isnt warm and fuzzy, and it brokers no sentimentality.
Atheism is nihilism for those who wish there to be more to life that what we find. To those who are not satisfied with what evidently is, all will seem inadequate. Lack of belief in an immortal soul and eternal life does not entail a devaluing of the life we have while we have it. Think about it - rarity, when it comes to desirable commodities, leads to a higher value being ascribed to those commodities. Your life, as an individual, is unique - why would not this lead to the highest of all values being ascribed thereto? If this life is all we get, surely that should lead us to make the most of it, not to write it off as unimportant.
But I do see one thing in your post worth a mention of a fundamental nature: eating, drinking, companionship, these things, of themselves, cannot make life “worthwhile”. Alone, they are nothing.
What else do you wish them to be, other than life-sustaining activities? Why should any experience lose its value if it is finite?
With objective meaning, purpose, and value in the universe, they all become infinitely important.
Yet if life is not infinite, it must still be temporally important to those who experience it - you cannot get away from that. We still exist for a time, and that time can never be denied its existence. All meaning is contextual - in the context of our temporal existence, all life experience is important. It can diminish in importance if one prefers to take an eternal view, much as the savour of a delicious meal, the delight of a moving musical phrase, the sweetness of a lover’s caress, can all diminish if we become accustomed to them.
If there is no eternal nature to our existence, nothing matters. If there is an eternal nature to our existence, EVERYTHING matters!
If we have not eternal existence, then our experience does not matter, ultimately, to the eternal universe (and by ‘universe’ I mean, ‘all that exists’). That does not mean it has no importance
for us, while we exist. That is the fundamental difference between clinging to the hope of an eternal self and reaching a full appreciation of what we have while we have it. Carpe diem!
