Humans can debate until the cows come home and never reach a conclusion, but creation as we know it is built deliberately flawed. Everything is flawed, our minds and all substance. Things are created (life, plant matter) then deliberately destroyed by a creator. It's as if a creator designed destruction in order that life does not gain invincibility.
Which brings on another theory that christians will hate, there is no devil. If life was created with a time limit, the 'devil' is a human excuse for a deliberately created force of resistance to invincibility. Newton's third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions. The 'creator' and the 'devil' are the same thing, creator and anti-creator, its all built into the design. Love and hate are opposites. Do christians call hate evil? There are lots of things christians hate, so it could it be said, the act of hate is devilish.
Hitchens was the light of his time, also a Marxist and chain smoker. Brilliance naturally prefers the efficiency of authoritarianism. Ignoring his bodies wish for moderation, he died from bad habits.
The creator sets things in motion and gives people free will. The creator is not deliberately destroying. That is, if there's a creator.
Ok, so the 'creator' is flawed/weak as well, it creates only for something else to come along and beat it down, undo its work? The Almighty devil again?
Do most people eventually learn from their mistakes as they go through life? And is the world a better place now than say 1,000 years ago? If so, then things are progressing.
Progress is finite, here today, gone tomorrow. Civilizations rise and crumble. Are we better off today? Mass shootings in cities etc, mass homeliness in 1st world countries, greater divide between rich and poor. Several nations bristling with nuclear weapons, Russia continually threatening, China getting stroppy. Are we better off than the 1960's 1970's...?
Mass shootings is in part due to the availability of guns and being able to kill many people with relative ease. It's not that people are worse now than previously. Is homelessness worse today than in the past? The rich poor divide is certainly less today compared to almost any time in history. Nuclear weapons: they haven't been used since 1945. Russia and the war in Ukraine: generally, war is on the decline. China getting stroppy: is only potential for escalation into something bad. It doesn't count if it hasn't happened yet. As a whole we're more evolved than a thousand years ago or than the 1960s/1970s. The awareness of the need to tackle climate change, LGBT rights, and the Internet. Not that it's a straight line, there are troughs. The 1960s and 1970s is a blip.
