Jesus was active in the work of God the Father in Eternity past. Eternity past is long before 6000 years ago. Jesus has been an active Creator long before the time of this creation recorded in Genesis and this evil age in God's history.

Jesus as He taught the Jews about His relationship and purpose in keeping the word and will of His Father told them of His existence even before Abraham.

John 8:58-59

58 Jesus said to them, "Truly, truly, I say to you, before Abraham was born, I am." NASB

Jesus as God's Son existed with the Father before the separated creation was made.

John 17:1-5

17 These things Jesus spoke; and lifting up His eyes to heaven, He said, "Father, the hour has come; glorify Thy Son, that the Son may glorify Thee, 2 even as Thou gavest Him authority over all mankind, that to all whom Thou hast given Him, He may give eternal life. 3 "And this is eternal life, that they may know Thee, the only true God, and Jesus Christ whom Thou hast sent. 4 "I glorified Thee on the earth, having accomplished the work which Thou hast given Me to do. 5 "And now, glorify Thou Me together with Thyself, Father, with the glory which I had with Thee before the world was. NASB

 

John 17:24

24 "Father, I desire that they also, whom Thou hast given Me, be with Me where I am, in order that they may behold My glory, which Thou hast given Me; for Thou didst love Me before the foundation of the world. NASB

John 1:1-3

1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was in the beginning with God. 3 All things came into being by Him, and apart from Him nothing came into being that has come into being.  NASB

Jesus came from God where He had been with God. He was from a region of God's creation where  man could no go now represented by the 3rd heaven.

John 8:21-30

21 He said therefore again to them, "I go away, and you shall seek Me, and shall die in your sin; where I am going, you cannot come." 22 Therefore the Jews were saying, "Surely He will not kill Himself, will He, since He says, 'Where I am going, you cannot come'?" 23 And He was saying to them, "You are from below, I am from above; you are of this world, I am not of this world. 24 "I said therefore to you, that you shall die in your sins; for unless you believe that I am He, you shall die in your sins." 25 And so they were saying to Him, "Who are You?" Jesus said to them, "What have I been saying to you from the beginning? 26 "I have many things to speak and to judge concerning you, but He who sent Me is true; and the things which I heard from Him, these I speak to the world." 27 They did not realize that He had been speaking to them about the Father. 28 Jesus therefore said, "When you lift up the Son of Man, then you will know that I am He, and I do nothing on My own initiative, but I speak these things as the Father taught Me. 29 "And He who sent Me is with Me; He has not left Me alone, for I always do the things that are pleasing to Him." 30 As He spoke these things, many came to believe in Him. NASB

 

John 18:33-37

33 Pilate therefore entered again into the Praetorium, and summoned Jesus, and said to Him, "Are You the King of the Jews?" 34 Jesus answered, "Are you saying this on your own initiative, or did others tell you about Me?" 35 Pilate answered, "I am not a Jew, am I? Your own nation and the chief priests delivered You up to me; what have You done?" 36 Jesus answered, "My kingdom is not of this world. If My kingdom were of this world, then My servants would be fighting, that I might not be delivered up to the Jews; but as it is, My kingdom is not of this realm." 37 Pilate therefore said to Him, "So You are a king?" Jesus answered, "You say correctly that I am a king. For this I have been born, and for this I have come into the world, to bear witness to the truth. Everyone who is of the truth hears My voice." NASB

 

John 1:1-3

1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was in the beginning with God. 3 All things came into being by Him, and apart from Him nothing came into being that has come into being.  NASB

Jesus was God...He was Light. The Deity of Jesus is verified by the witness of God the Father, angels, apostles,  prophets and even demons.

Matthew 3:13-17

13 Then Jesus arrived from Galilee at the Jordan coming to John, to be baptized by him. 14 But John tried to prevent Him, saying, "I have need to be baptized by You, and do You come to me?" 15 But Jesus answering said to him, "Permit it at this time; for in this way it is fitting for us to fulfill all righteousness." Then he permitted Him. 16 And after being baptized, Jesus went up immediately from the water; and behold, the heavens were opened, and he saw the Spirit of God descending as a dove, and coming upon Him, 17 and behold, a voice out of the heavens, saying, "This is My beloved Son, in whom I am well-pleased."  NASB

 

Matthew 1:18-25

18 Now the birth of Jesus Christ was as follows. When His mother Mary had been betrothed to Joseph, before they came together she was found to be with child by the Holy Spirit. 19 And Joseph her husband, being a righteous man, and not wanting to disgrace her, desired to put her away secretly. 20 But when he had considered this, behold, an angel of the Lord appeared to him in a dream, saying, "Joseph, son of David, do not be afraid to take Mary as your wife; for that which has been conceived in her is of the Holy Spirit. 21 "And she will bear a Son; and you shall call His name Jesus, for it is He who will save His people from their sins." 22 Now all this took place that what was spoken by the Lord through the prophet might be fulfilled, saying, 23 "Behold, the virgin shall be with child, and shall bear a Son, and they shall call His name Immanuel," which translated means, "God with us." 24 And Joseph arose from his sleep, and did as the angel of the Lord commanded him, and took her as his wife, 25 and kept her a virgin until she gave birth to a Son; and he called His name Jesus. NASB

Luke 8:26-28

26 And they sailed to the country of the Gerasenes, which is opposite Galilee. 27 And when He had come out onto the land, He was met by a certain man from the city who was possessed with demons; and who had not put on any clothing for a long time, and was not living in a house, but in the tombs. 28 And seeing Jesus, he cried out and fell before Him, and said in a loud voice, "What do I have to do with You, Jesus, Son of the Most High God? I beg You, do not torment me." NASB

 

Mark 3:11

11 And whenever the unclean spirits beheld Him, they would fall down before Him and cry out, saying, "You are the Son of God!" NASB

John 1:1-3

1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was in the beginning with God. 3 All things came into being by Him, and apart from Him nothing came into being that has come into being.  NASB

 

Colossians 1:9-23

For this reason also, since the day we heard of it, we have not ceased to pray for you and to ask that you may be filled with the knowledge of His will in all spiritual wisdom and understanding, 10 so that you may walk in a manner worthy of the Lord, to please Him in all respects, bearing fruit in every good work and increasing in the knowledge of God; 11 strengthened with all power, according to His glorious might, for the attaining of all steadfastness and patience; joyously 12 giving thanks to the Father, who has qualified us to share in the inheritance of the saints in light. 13 For He delivered us from the domain of darkness, and transferred us to the kingdom of His beloved Son, 14 in whom we have redemption, the forgiveness of sins. 15 And He is the image of the invisible God, the first-born of all creation. 16 For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities — all things have been created by Him and for Him. 17 And He is before all things, and in Him all things hold together. 18 He is also head of the body, the church; and He is the beginning, the first-born from the dead; so that He Himself might come to have first place in everything. 19 For it was the Father's good pleasure for all the fulness to dwell in Him, 20 and through Him to reconcile all things to Himself, having made peace through the blood of His cross; through Him, I say, whether things on earth or things in heaven. 21 And although you were formerly alienated and hostile in mind, engaged in evil deeds, 22 yet He has now reconciled you in His fleshly body through death, in order to present you before Him holy and blameless and beyond reproach — 23 if indeed you continue in the faith firmly established and steadfast, and not moved away from the hope of the gospel that you have heard, which was proclaimed in all creation under heaven, and of which I, Paul, was made a minister. NASB
