We've answered this multiple times already. This is the last time. Yeshua, being God and part of the triune God, lowered Himself and became human to provide the perfect sacrifice for the sin of mankind. While He was here on earth, He communicated with the Father through prayer, just like we do, because He was human. Thus, He, being God, prayed to the Father, also God, because He was human and voluntarily lowered Himself. Now, if you keep asking the same question, it's obvious that you're simply ignoring the answer.
