Well then, you don't know your Bible very well.
There is ONE God.
God is Father; Jesus always called God "my Father" and taught us to do the same.
God is Son; Jesus was accused of blasphemy and almost stoned because he claimed to be God, John 5:18, John 10:33. He used the name of God revealed to Moses - I AM, Exodus 3:14, John 8:58, John 14:6, John 15:1, John 11:25.
God is Spirit, John 4:24. All through the OT we read about the Spirit of the Lord. Jesus told his disciples that the Spirit knows the things of God and will make them known to them.
The Father is eternal, Genesis 1:1, Revelation 1:8. He created the world and was there in the beginning.
The Son is eternal, John 1:1-2, Colossians 1:15, Hebrews 1:3, John 17:5, Revelation 1:17-18.
The Spirit is eternal, was present at creation and gave life to mankind, Genesis 1:3, Genesis 2:7.
All 3 members of the Trinity are involved in our salvation; we have sinned against the Father, Jesus is the only way to the Father, John 14:6, and came to reconcile us to God, 2 Corinthians 5:18, Romans 5:11, and the Spirit draws us to Jesus, causes us to be born again, John 3:3 and assures us that we are God's children, John 1:12, Romans 8:16.
In Genesis 1:26 God said "Let US make man in OUR image". The word for God used here is plural. In Genesis 11:7 he said "let US go down and confuse their language". In Isaiah 6:8 God said, "whom shall I send and who will go for US?"
In Matthew 28:19 Jesus told his disciples to baptise in the name of the Father, the Son and the Holy Spirit. Paul blessed the church at Corinth in the name of the Father, the Son and the Holy Spirit, 2 Corinthians 13:4.
Those verses are just off the top of my head, without doing an in-depth study.
Seriously, if you rely on ONE verse to teach you an important doctrine, you don't understand the Bible very well.
No they wouldn't, because of the verse that I have posted above, and others.
You may prefer to believe that the KJV is the only Bible that shows, and teaches, that there is one God in 3 persons - but it's not.
