Hello again OneFaith, the Bible tells us that God "created the heavens and the earth" (Genesis 1:1) BEFORE He called light into existence by saying, "let there be light".
So, if what you believe is true (that the Lord Jesus is actually the "light" that God created in Genesis 1:3 .. which He called "day" in v5), then you are not correct about Him creating "all things" (as the big daddy of all Creation, the Universe itself, was created PRIOR to God calling "light" into existence).
Actually, God made it clear for us that there is ONE God, period, and that He is the only God who will ever exist. For instance,
Deuteronomy 6
4 “Hear, O Israel! The LORD is our God, the LORD is one!
Isaiah 43
10 “You are My witnesses,” declares the LORD,
“And My servant whom I have chosen,
In order that you may know and believe Me
And understand that I am He.
Before Me there was no God formed,
And there will be none after Me.
11 “I, even I, am the LORD,
And there is no Savior besides Me.”
The Bible tells us plainly that there is ONE Divine "Being" who we refer to as "God". However, the Bible also makes it clear that this one and only God has ~always~ existed/will always continue to exist as THREE, distinct "Persons". One Divine Being/God existing both from and to everlasting as three distinct Divine Persons is what the Bible tells us about Him.
God has ALWAYS existed. He was not created (or "born"). The same is, of course, true of all three Members of the Godhead, the Father and the Son and the Holy Spirit. That said, God the Son, who existed from everlasting with a Divine nature, was incarnated (born) about 2,000 years ago and took on a second, human nature at that point in time, and so He continues to exist today in Heaven, as the God/man with both a Divine and a human nature (and a now glorified human body).
Hope that helps
