Man is made in the image of the Father
The Father spoke all of everything into existence by his Word
The Father breathed into the man's nostrils and he became a living spirit.
-------Literally first two pages of the Bible paraphrase
You being in the image of God speak your word by your breath (spirit). Are you, your word, and your breath/spirit three different people or one person?
You are the proof of the triune God.
I suppose you are searching for the text stating that God is Trinity.
So far your score is nil but keep up!!!
In the mean time I will point you to some of the fool-proof texts:
