What have you possibly done that a few millennium can't forgive you for?
Why do you think that you deserve all existence forever?
Who convinced you to let go fo the miracle of your own life?
It's just something that I don't care to hear, but whatever you convince yourself of know that the opposite is true by default.
It's part of existing inside of a universe of possibility. Possibility to create something good is as real as anything else. And creating life is as real as the life that created it.
