Not to speak for Hatter or anyone else, but I don’t think anyone “likes” the fact that we will die or that it’s very likely that memory of us will not last very long. However, that should not keep one from living one’s live well, learn well and doing what one can to improve this world. Theists keep pinning their delusions on being rewarded by some magical being after they are dead. Nothing supports this myth, as nothing supports your feeling that a “creator exists somewhere”. You want to feel like you have some meaning, that this big important creator cares about you, which in turn makes you feel big and important. That seems rather immature to me, the needs of someone who needs external validation.
If I were offered eternal life on this planet would I take it? Yep, sure. And I’d spend that life doing exactly as I am doing now, living live well and trying to improve the planet, trying to understand everything (and not whining that it’s okay not to understand as an excuse) and then hopefully the solar system, the local stars, the galaxy and on and on. But since I doubt that will happen, I am doing that anyway. I don’t fear death for myself. I fear the loss I will feel when those I love die. I do fear pain, if that’s involved, but death? No, it’s just part of life. I was non-existing before I was born and I will be non-existing afterwards. I don’t need a primitive delusion, no matter how kitted out in new age nonsense or some new interpretation of some moldy “holy book” to make things feel better.
