Oh, the earlier version of moist robots from the process of developing primordial slime?
If we are just molecules in motion , then we are nothing but moist robots whose every thought is the result of a previous natural cause. Free-thinking can’t exist in such a world. Ironically, atheists must rely on faith rather than reason. Being materialists, atheists Sam Harris and Daniel Dennett claim that consciousness, and free will are illusions (one wonders if they freely came to those conclusions while conscious!). But if they are correct, then “you” and “me” don’t really exist in a conscious state and so neither do arguments—we are just molecular machines who are just reacting not reasoning.
This is the central problem that emerges repeatedly in atheist arguments: Atheists exempt themselves from their own claims and theories. If free will is an illusion and everyone is a molecular machine, then we can’t reasonably arrive at any conclusions.
