“It seems that you missed the Bible passages where God the Father explicitly declares, “Hello children, I am the one and only God in town.”
That was Jesus.
“For unto us a Child is born, unto us a Son is given; and the government shall be upon His shoulder. And His name shall be called Wonderful, Counselor, The Mighty God, The Everlasting Father, The Prince of Peace.”
Isaiah 9:6
“I have an abundance of evidence to demonstrate that the Holy Spirit is not a person.”
List on, please.
I’ll start by listing the verses that demonstrate God the Holy Spirit is as much God as is the Son and the Father.
"As an integral part of the Godhead, the Holy Spirit has existed from eternity, and the Bible reveals Him as a person, not an impersonal force. He strives, as we read in Genesis 6:3 where the Lord says, “My Spirit shall not strive with man forever . . .” He teaches, as indicated in Luke 12:12, “For the Holy Spirit will teach you in that very hour what you ought to say.” He convicts, as we noted in John 16:8. In Acts 13:2, we see Him directing in church affairs.
In Romans 8:26 we read this beautiful description: “Likewise the Spirit also helps in our weaknesses. For we do not know what we should pray for as we ought, but the Spirit Himself makes intercession for us with groanings which cannot be uttered.”
He inspires, as indicated in 2 Peter 1:21—“for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit.” And He sanctifies, as 1 Peter 1:2 refers to “the foreknowledge of God the Father, in sanctification of the Spirit, for obedience and sprinkling of the blood of Jesus Christ.”
The Holy Spirit was active at Creation, “hovering over the face of the waters” (Gen. 1:1,2). David knew Him when he cried out in Psalm 51:11, “Do not cast me away from Your presence, and do not take Your Holy Spirit from me.”
We see the role of the Holy Spirit in the incarnation of Jesus Christ when an angel told Mary, as recorded in Luke 1:35, “'The Holy Spirit will come upon you, and the power of the Highest will overshadow you; therefore, also, that Holy One who is to be born will be called the Son of God.”
Jesus Himself acknowledged the anointing of the Holy Spirit when He read from Isaiah 61:1— “The Spirit of the Lord God is upon Me, because the Lord has anointed Me to preach good tidings to the poor; He has sent Me to heal the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to those who are bound.”
Shortly before His crucifixion, Jesus assured His disciples: “These things I have spoken to you while being present with you. But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you” (John 14:25, 26).
Just 50 days later, Christ’s promise to His disciples was fulfilled, as recorded in Acts 2:1-4 “When the Day of Pentecost had fully come, they were all with one accord in one place. And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. Then there appeared to them divided tongues, as of fire, and one sat upon each of them. And they were all filled with the Holy Spirit . . .”"

Please take note of the number of times, the Holy Spirit is referred to with the personal pronoun, he.
And with all of this He is said to be active in doing something.
“In Matthew 12:31, 32 we read: “Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men. Anyone who speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come.””

" Therefore, go and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit (Matthew 28:19 NLT).
Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons (1 Timothy 4:1 ESV).
Mar 3:29-30 KJV - 29 But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation: 30 Because they said, He hath an unclean spirit."
For it has seemed good to the Holy Spirit and to us to impose on you no further burden than these essentials (Acts 15:28 NRSV).
But when the Counselor comes, whom I shall send to you from the Father, even the Spirit of truth, who proceeds from the Father, he will bear witness to me; and you also are witnesses, because you have been with me from the beginning (John 15:26-27 RSV).
As they ministered to the Lord and fasted, the Holy Ghost said, “Set apart for Me Barnabas and Saul for the work to which I have called them.”
Acts 13:2
