Jesus pray to the father “The only True God” ?

If Jesus was God why then he was praying to the Father in John 17:3 ?

And this is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent.

Why christians worship The Lord Jesus? Because we read in the same Gospel of John that the authority of judgement and honor was giving to the Son by the Father in John 5:22-23 therefore we ought to honor the Son with the same honor that we give to the Father:

For the Father judges no one, but has given all judgment to the Son, ²³ that all may honor the Son, just as they honor the Father. Whoever does not honor the Son does not honor the Father who sent him.
John 5:22-23

Lord Jesus can answer prayers from heaven himself in John 14:13-14 if we ask in his name (something only God can do):

Whatever you ask in my name, this I will do, that the Father may be glorified in the Son. ¹⁴ If you ask me anything in my name, I will do it.
John 14:13-14

Jesus healed blind man and accept his worship in john 9:35-38:

Jesus heard that they had cast him out, and having found him he said, “Do you believe in the Son of Man?” ³⁶ He answered, “And who is he, sir, that I may believe in him?” ³⁷ Jesus said to him, “You have seen him, and it is he who is speaking to you.” ³⁸ He said, “Lord, I believe,” and he worshiped him.”
John 9:35-38

If Jesus was a mere creature how can he give eternal life to all flesh ?

When Jesus had spoken these words, he lifted up his eyes to heaven, and said, “Father, the hour has come; glorify your Son that the Son may glorify you, ² since you have given him authority over all flesh, to give eternal life to all whom you have given him.
John 17:1-2

 

Why Jesus said to the Father he’s the only true God?
because he is only true God not exclusion of the Son. We also read in the same chapter in John 17:5 that Jesus asked to be glorified with the same glory he had along side of the Father before the world was created:

And now, Father, glorify me in your own presence with the glory that I had with you before the world existed.
John 17:5

The Lord Jesus as a man he was directing worship to the Father to be an example for his fellow-men in his ministry on earth.

In Christ,
