A scientist who believes only in himself as a deity still comes up with cures to ease pain and end disease. They worship the levels of evolution. So, their lives are short. GOD does not kill them, but He allows Lucifer and nature to take their toll of people who are ungodly. They do not go to hell but return to their own soul and wait and learn who GOD really is.
Death is part of earthly existence.
You can corrupt the body and spirit but the soul is a duplicate of the Creator. Your real estate, your star, waits for you. In the days of Adam and Eve, people lived 100 years or more, but mankind has corrupted the word and darkened himself in the truth. Only individuals were left who kept their minds and hearts open. But because people have placed themselves in a corrupt category of humanism, you cannot see Him right in front of you.
