Great breakdown! I have had this discussion a few times with my coworkers and it goes right above their heads. I love the plug of possibilities 😁

I think you are right when you state the free will to change the time line we are in, looking at the double slit experiment I think proves it’s our perception that manifests reality around us. Now I believe we are a slice of the higher dimension yet I don’t think we are determined otherwise the existence of the lower dimension would not be required from the perspective of a being that could be greater then time itself.
