unsure,
The LORD is God. He created the heavens and the earth alone, by himself with no one else.
24"Thus saith the LORD, thy redeemer, and he that formed thee from the womb, I am the LORD that maketh all things; that stretcheth forth the heavens alone; that spreadeth abroad the earth by myself;" Isaiah 44:24 KJV
"Which alone spreadeth out the heavens, and treadeth upon the waves of the sea." Job 9:8 KJV
Since He did it ALONE, then anyone that was involved in the creation of the heaven and the earth MUST be the LORD (Jehovah).
Hebrews 1:10 clearly shows that the heavens and the earth are the work of the hands of the the Lord Jesus Christ.
"And, Thou, Lord, in the beginning hast laid the foundation of the earth; and the heavens are the works of thine hands" Hebrews 1:10
Therefore The Lord Jesus is Jehovah.
