The contention in the opening post is that Michio Kaku is referring to a deity. Obviously, this isn't the case.
Try again to understand that when you say 'a deity' the word 'deity' is an abstraction, okay? It has no meaning except that which is attached to it by the speaker. Do you understand? This is how words work. Let me illustrate this in the simplest way I can (I presume you comprehend basic 'variables', yes?):
X = ?
The above illustrates the abstract word with X. Now, we do not have a definition of X. Whatever is placed into the ? by the speaker is the definition of X; so if I would say to you "Time exists" then "X exists" is my proposition. Now you would need to ask "What is your definition of X(Time)?" and then suppose I reply "Motion", so now we have:
X = Motion
It is that simple. So now you know that when I use the word "Time" I am refering to the physical process of motion. Now we can discuss "time" in a meaningful way because we both understand it is simply an abstraction for "motion" according to the way the speaker is defining the term. Now, if you were to say "time is not motion" you would be guilty of equivocating. What is happening in this process is that you - a different speaker - has a different definition of "time" which is causing you to engage in a communication breakdown where the above becomes a conflict of understanding. Suppose then that you define "time" as "space" (an illustration):
X = Space
Now, you are not comprehending the process of definition of terms, and so your mind is struggling with you inserting your own definition into the variable X that the speaker is defining, so it looks like this (following from the speakers 'X = Motion' and your 'X = Space':
Space = Motion
Now in your mind you are perceiving a 'silly word game' but your perception is a result of your inability to comprehend the liguistic function of defining terms. So your mind is creating a falsely perceived context in which 'my definition of X != his definition of X: and so he is playing a silly word game': BUT, if you understood the basic process of definition of terms, you would understand that X
has no definition until it is
defined by the one proposing the thought; it is nothing more than a
definition of term which provides defining of a term being evaluated by the speaker, and allowing both of you to be on the same page while discussing the concept. Can you understand?
So the basic problem is that you have had the term 'God' defined by others as 'man who lives in the sky and makes the universe' and so now, in your mind, you have been trained to attach the concept 'man who lives in the sky' to the abstraction of the word 'God' so when someone says "Define 'God'" in your untrained mind the request becomes "Define 'man who lives in the sky'" but it should not be understood this way: the request should be understood as "Define 'UNKNOWN ABSTRACTION'". But since you're not comprehending the basic process of defining terms, then when I define "UNKNOWN ABSTRACTION (i.e. 'God')" as "Sum of Consciousness" then in your mind it becomes:
"Man who lives in sky = Sum of consciousness" and your mind struggles with the statement; when in fact to the understanding mind the statement is "UNKNOWN VARIABLE = Sum of consciousness": are you understanding?
