I have repeatedly posted what John is saying, and you have left it unaddressed just as many times.
Joh 1:1 In the beginning was the Word, and the Word was with God, and the Word was God. (ESV)
"In the beginning was the Word," that is, when the beginning began, the Word was already in existence, and hence, had always been in existence. "And the Word was with [the] God"--"God" contains the article, and is therefore a reference to the Father. "With," being
pros, means "intimate relationship" and "communion." "The Word was God" refers to the nature of the Word, as "God" doesn't have the article. That is, the Word is of the same substance as the Father.
To sum then, the Word had eternal pre-existence, in intimate relationship with God (the Father), and was in nature deity himself. Yet, we know there was only one God. Hence, one reason why the Trinity best takes into account all that God reveals of himself--there is plurality within the one God.
What John says utterly contradicts your position. Your argument is against the Bible and what God reveals about himself. And, remember, this is John's prologue, the whole purpose of which is to tell us who the Word is and that the Word became flesh. So, everything else John says in his gospel has to take this into account, as it forms the foundation.
What else does John say that supports what I have said about John 1:1? Let's take a look:
Joh 3:13 No one has ascended into heaven except
he who descended from heaven, the Son of Man.
…
Joh 3:16 “For God so loved the world, that
he gave his only Son, that whoever believes in him should not perish but have eternal life.
Joh 3:17 For God did not
send his Son into the world to condemn the world, but in order that the world might be saved through him.
Joh 6:38 For
I have come down from heaven, not to do my own will but
the will of him who sent me.
…
Joh 6:62 Then what if you were to see the Son of Man
ascending to where he was before?
Joh 14:23 Jesus answered him, “If anyone loves me, he will keep my word, and
my Father will love him, and we will come to him and make our home with him.
Joh 14:24 Whoever does not love me does not keep my words. And
the word that you hear is not mine but the Father's who sent me.
Joh 16:27 for
the Father himself loves you, because you have loved me and have believed
that I came from God.
Joh 16:28
I came from the Father and have come into the world, and now I am leaving the world and going to the Father.”
Joh 16:29 His disciples said, “Ah, now you are speaking plainly and not using figurative speech!
Joh 16:30 Now we know that you know all things and do not need anyone to question you; this is why we believe
that you came from God.”
Joh 17:5 And now,
Father, glorify me in your own presence with the glory that I had with you before the world existed.
..
Joh 17:8 For I have given them the words that you gave me, and they have received them and have come to know in truth that
I came from you; and they have believed
that you sent me.
...
Joh 17:23 I in them and you in me, that they may become perfectly one, so that the world may know that
you sent me and loved them
even as you loved me.
Joh 17:24 Father, I desire that they also, whom you have given me, may be with me where I am, to see my glory that you have given me because
you loved me before the foundation of the world.
Look at how many times Jesus says that he existed with the Father prior to his incarnation. He also says that he shared the Father's glory "before the world existed," that is, before creation. So, just as John states in John 1:1-2, the Word, the pre-incarnate Son, existed in intimate relationship and communion with the Father for all eternity past.
There is no division, it is distinction. They are all of the one indivisible substance or essence that is God. One God, three persons.
I did clarify it, you just seem to be purposely twisting what it says to fit your theology.
Simplifying the diagram cannot be done. It is as simple as it can be to truthfully communicates the biblical Trinity.
