The law of existence is eternal. Maybe there are worlds where the laws of physics are different, but there is no possible world in which there is such a thing as a “square triangle”. A scientific law is not necessarily a logical law, but rather it is an observance of physical behaviors that are
consistent enough to deserve being called a “law”. Perhaps there is a world in which bricks don’t smash windows and blue elephants can at any moment burst out of acorns. Perhaps there is a world where things move without a mechanistic cause. But that is not the same as saying that there is an objective nature that is nothing or that i can exist and not exist at the same time. The laws of “being” and the laws of physics are two different things. When we talk about the act of existence we are talking about the laws of metaphysics, not physics. Physics deals with the essence or nature of that which happens to be actual. For instance science analysis the size shape width and weight of a thing and also the particular kind of power that a thing has. Metaphysics deals with reality in general as an “act” as opposed to that which is nothing at all. The laws of being is that which is necessarily true; and the laws of physics is that which is a potential consequence of the laws of being. The laws of physics can be different, but they can never contradict reality.
There is one thing that is certainly true of all “worlds”, and this is the fact that they “exist”. They are real or have the potentiality to be real. You cannot have a world that is nothing, because a “world” by definition is something; it is a real circumstance to which objectively true statements can be applied. A world cannot be and not be at the same time, and this is because “reality” as an “act” is
fundamentally logical. You cannot have something which is objectively nothing, for nothing has no objectivity in it in so far as it has no reality; and there can be no such thing as an objective truth that is nothing, since there is no objective truth in nothing. Therefore out of nothing comes nothing. Thus there must be a being which has an essence that is fundamentally the same as its existence, and is thus the eternal root of all potential realities; otherwise
no potential reality can exist. A potential reality is not existence by its own nature because if it was it would not fail to exist; it would timelessly transcend all potential reality. Potential realities gain reality only by
participating in that which is reality. By themselves, they have no reality or nature. They are generated and sustained in reality by that which is absolute existence.
In order words a potential being cannot actualize itself for the simple fact that it is not real.
This thread is not for what you two are talking about, so start a new thread
I am glad that you are taking it seriously.
We can verify the “existence” of God metaphysically. Metaphysical knowledge is certain knowledge. It cannot not be true.
