I believe that Jesus/Christ in some way/form existed before Genesis 1:1/John 1:1.
John 1:1,2
In the beginning was the Word, and the Word was with God, and the Word was God.
The same was in the beginning with God.
Speculating is something the demons seek to get people in to which leads to departing from what the Lord says which leads to departing from the Lord. Besides, John 1:1,2 tells us about "
in the beginning" which is all we need to know and of course that is speaking of before Genesis 1:1.
Anytime the Lord does not directly address something in His Word it means it's a non-issue and the Lord does not need for man to know about it now. Once we get to be with Him in Heaven we will know as we are known (
1 Corinthians 13:12) so relax, when the time comes we'll have all the details.
