"Mami says its our spirits that make us human."

what about animals then?

Essentially animals do not. Humans are unique as we are made in the image of God, which consists of the trinity which includes the Holy Spirit.

So where do they go? Are they vessels emptied of life? Never to be found again except in the fragments of memory we have of them. The Bible talks about the rapture, the Resurrection of souls in the end days, but animals with no souls, where do they go?

Isn't it better then? To know that there will neither be eternal damnation nor paradise, to not be worried about where you are headed.

Because death scares us. But what we fear is what comes after, the mystery of the unknown that plays with our imagination.
