I assume “Yes”.
Do I know what this body of knowledge is? No…
Does my lack of knowledge preclude it’s existence? No…
Nope. Why should I?
First of all - please recognize that my initial answer was to your initial questions. That is - - there is no conflict between the statements you made.
Now one can (as you have done) ask why and how a designer might choose to do what is proposed in the OP…but that is secondary to the question of whether it is possible. It is indeed possible.
OK - - to reply to your questions above.
Someone cuts me off in traffic. I am “designed” with two very basic options. I can get angry or not get angry…I have free will to choose which one…Further - I have many variations of choice that stem from these very basic binary choices. I can not become angry, but still be upset. I can just let it pass and add a prayer for that person.
Consciousness is what actually ALLOWS me to choose. Without the conscious will, I would act instinctively - that is - without free will.
Again - no conflict.
Peace
James
