Death is normal too but I don't take it as lightly as you do. Maybe that is your advantage as a religious person, to you death is like stepping through a door, no big deal so if people die, that is fine. As an atheist I consider life, especially human life, to be special and priceless and don't want to see it thrown away with little thought.Yes, extinctions are quite normal. Are you trying to stop them from happening? Do you think we can control them like you think we can control the weather?
