John 1:18
No one has ever seen God. The only Son, God, who is at the Father's side, has revealed him. -NAB
No one has ever seen God, but God the One and Only,[a]who is at the Father's side, has made him known. -NIV
No one has seen God at any time; the only begotten God who is in the bosom of the Father, He has explained Him. -NASB
These are only a sample of the majority of biblical translations. John 1:18 shows directly that Jesus is God and is begotten of the Father.
Jesus knew the Father more than anyone else because He is begotten of the Father and shares in being with Him.
