I understand that, but without a "God"-like figure to create the Submachine, how does
this happen?
All my theory states is that the submachine or whoever created the submachine programmed it to spawn the plan.
By saying
who, you contradict your Theory: The "who" would then be the "Architect."
If the Submachine itself created the Plan, then that
also answers the "who" in the question "Who is the Architect?"
It's either there's a "Big Bang," meaning the SubNet was spontaneously created as well as the Plan, or Creationism, meaning the Architects built it. If Creationism is the answer, your Theory is Debunked.
