The basic meaning of the world *el* is power or strength. It does not always designate "God" -- the Supreme Being -- as that word is often used of Jehovah, or false god as it may be used of idols. When used of others than Jehovah or idols, it often simply takes the meaning of strength, power, might. (See Proverbs 3:17 and Micah 2:1, where the KJV translated *el* as "in the power of "; see also Strong's Hebrew Dictionary for #410) "Formed" applies to the idols, not to Jehovah. Jehovah himself was never formed, for he has always been, so therefore there could be no idol-god formed before Jehovah, and he will always be, so there can be no idol-god formed after him
The sons of God are called "elohim" in Psalm 82:6 are not equal to Jehovah, nor will they ever be. (Psalm 8:1) Moses, who was made elohim [god] to Pharoah by Jehovah himself, is not made equal to Jehovah, and he will never be equal to Jehovah. Likewise, Jesus is not equal to his Father, Jehovah, the only true God [Supreme Being], nor will he ever be. (John 17:1,3; Psalm 45:7)
The Bible itself refers to others as elohim and theoi, thus we need to note the relative difference in the usage of the word. Indeed, in some of the scriptures it is Jehovah Himself who uses the Hebrew word for "God/god" of others than Himself.
You are misinterpreting this verse. This verse does not mean Jesus is God. The specific "gods" being referred to are the idol-gods of men. (2) Jesus was not brought forth before or after God, since Jehovah had no beginning and had no end. Nor was Jesus brought forth as God [The Supreme Being], or equal to God. He was brought forth as mighty -- as a mighty being, but not as God Almighty.
Jehovah, the God and Father of Jesus is the only true God in the absolute superlative usage of the word God -- the sole Power; the monotheistic belief in one true Supreme Being. Jesus is not the Supreme Being who sent him.
