Glad you are in a good place. I like the idea of this life being just a first step, a trial run so to speak of the things to come for humans. I like the idea that a non biblical higher being got things started at a molecular level and had a plan for humans to achieve incredible things.
I also read fiction and love it even though I know it's fiction.
It's just my opinion, but I'd say that like every other organism that has a shelf life (all of them) when we die, that's all she wrote. The thought gives me heart palpitations (because i want to live), but I think I'm slowly coming around to the reality of my mortality. All we can do is live a meaningful, productive life, trying to make this planet a little better than it was before we came into it. We control what we can and find peace in doing that.
