My friend, you simply don't understand the concept of the Trinity.
There is one God in three persons.
The Father, Son, and Holy Spirit are one God but able to interact with each other.
Hard for us mere humans to understand, but correct and consistent throughout the Old and New Testaments.
Jesus said, "Anyone who has seen Me has seen the Father."
And from Isaiah 9:6 (go look yourself):
For a child will be born to us, a son will be given to us; And the government will rest on His shoulders; And His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace. There will be no end to the increase of His government or of peace, On the throne of David and over his kingdom, To establish it and to uphold it with justice and righteousness From then on and forevermore. The zeal of the LORD of hosts will accomplish this.…
