Concerning the questioin, "Did Time Always Exist?" It seems there is a tremendous lack of Biblical response to a simple inquiry about one of "the first principles of the oracles of God" (Hebrews 5:12). "In the beginning God created the heaven and the earth" (Genesis 1:1), but it did not say he created "time". Howbeit, most falsely so called "theologians" and their illegitimate ecclesiastical offspring "Bible Scholars" have wasted 2,000 years of history writing volumes about "when" was "the beginning". That in itself is a colossal failure to understand that "the beginning" is not a time or place in history, as if "time" could be located and pin pointed in man's vain attempt to grasp their imaginary "universe" as a replacement for eternity. Brethren, Jesus Christ said repeatedly, "I AM the beginning and the ending" (Revelation 1:8/ 21:6/ 22:13), so much so, that for the Bible to say, "In THE BEGINNING God created the heaven and the earth" (Genesis 1:1) is nothing removed from also saying, "In Jesus Christ God created the heaven and the earth". That is why Paul stated, "IN HIM we live, and move, and HAVE OUR BEING" (Acts 17:28). Likewise saith the New Testament, that "In THE BEGINNING was the Word, and the Word was with God, and the WORD WAS GOD" (John 1:1). "The SAME was IN THE BEGINNING WITH GOD" (vs. 2). Jesus Christ IS "the beginning", and In Jesus Christ WAS THE WORD, and WORD was with God, and the WORD WAS GOD", and "the WORD WAS made flesh" (John 1:14) when "GOD WAS manifest in the flesh" (1 Timothy 3:16). Brethren, "the beginning" is not a time period, but the person of Jesus Christ for all eternity. And to find the answer to the question about the existence of "time", one only has to look at the Beginning and the End as the same person to find the answer.
Jesus Christ being "the beginning and the end", the two are the same in Christ Jesus, so that in looking at the creative acts of God in Genesis 1, the deafness and blindness of modern Bible scholars prevents them from hearing or seeing what God clearly said and shewed them about when exactly did God "create the heaven and the earth". God asks this of the theological blind leaders of the blind, "Thou hast heard, see all this. And will ye not declare it? I have shewed thee NEW THINGS from THIS TIME, even hidden things, and thou didst not know them. They ARE CREATED NOW, and NOT FROM THE BEGINNING; even BEFORE the day when thou heardest them not; lets thou shouldest say, Behold, I knew them. BEHOLD, thou heardest not. Yea, thou knewest not. Yea, from THAT TIME thine ear was not opened." (Isaiah 48:6-8). That eternal statement was followed with "I AM HE. I AM THE FIRST, I ALSO AM THE LAST" (vs. 12), with this admonition to even an unbelieving, Bible believing 'antichristianity', "Com ye near unto me, hear ye THIS! I HAVE NOT SPOKEN in secret from THE BEGINNING. From the TIME THAT IT WAS, THERE I AM; and NOW THE LORD GOD" (48:16). To understand the existence of time, one must needs only look at "THE END from THE BEGINNING, and from ANCIENT TIMES the things that are not yet done" (Isaiah 46:10), and it that view of "THE END from THE BEGINNING", you will discover a point near "THE END" where God says, "there should be TIME no longer" (Revelation 10:6).
"Time" in the Bible is first mentioned as a process (Genesis 4:3) not a period or location. And "time" is a process that the Bible and the modern vernacular say "happeneth to them all" (Ecclesiastes 9:11). Time happens! That process is first spoken of in the New Testament concerning "WHAT TIME the star appeared" (Matthew 2:7, 16) that announced the birth of Christ, the Holy Ghost translating "time" (see Hebrews 11:5 metathesis) from where the English word 'chronology' comes from. Time, as does matter and space, does not exist in eternity, or eternity would not be eternal. Eternity is mentioned only once in the Bible and is spoken of as "the High and Holy Place", that God Almighty "inhabiteth" (Isaiah 57:15). As such, it is a place limited to only those who have "life eternal", which is defined as "This is life eternal, that they might know Thee the Only True God, and Jesus Christ, Whom Thou hast sent" (John 17:3), which John wrote further in identifying Jesus Christ as God and life eternal, saying, "And we know that the Son of God IS COME, and hath given us an understanding, that we may KNOW HIM that IS TRUE, and we ARE IN HIM that IS TRUE, even IN HIS SON JESUS CHRIST. This IS THE TRUE GOD, and ETERNAL LIFE" (1 John 5:20).
As "THE TRUE GOD, and ETERNAL LIFE", Jesus Christ as "God manifest in the flesh" (1 Timothy 3:16) is both "the Son of God" and "the Son of Man", about the latter of which the Word of God that was made flesh and dwelt among us (John 1:14) said very clearly, "GOD IS NOT A MAN, neither the Son of Man" (Numbers 23:19), setting in motion "the end from the beginning, and from ancient times the things that are not yet done" (Isaiah 46:10), concerning "who is the Son of Man?" (John 12:34). There is an aspect of Jesus Christ that is the eternal manifestation of "the beginning and the end", as much as He is also "the First and the Last" (Revelation 1:11, 17/ 2:8/ 22:13), which latter attribute calls time for all generations from the beginning (see Isaiah 41:4/ 44:6/ 48:12).
As "the First and the Last", Christians must "from the beginning" (Isaiah 46:10) deal with the creation of the first man, which God Almighty said from the beginning, "Let US make man in our own image, after OUR likeness" (Genesis 1:26), the end of which concluded that "So God created man IN HIS OWN IMAGE, IN THE IMAGE OF GOD created He him" (1:27), identifying for all eternity that "Christ...is the image of God" (2 Corinthians 4:4), even "the image of the Invisible God" (Colossians 1:15) by whom "were all things created, that ARE IN [present tense] heaven, and that ARE IN [present tense] earth, visible and invisible, whether they BE [present tense] thrones, or dominions, or principalities, or powers: all things WERE [PAST tense] created by Him, and for Him: and HE IS BEFORE all things, and by HIM all things CONSIST" (Colossians 1:16-17). They consist and exist by Him, to the very "end from the beginning" (Isaiah 46:10), and from the first until the last second of time no longer (Revelation 10:6). Then it will turn upon Christ alone, who being "THE FIRST and THE LAST", even "THE FIRST born of every creature" (Colossians 1:15), and "the first born from the dead" (vs. 18), to manifest in and for all eternity the timeless "Revelation of Jesus Christ" (Revelation 1:1) by which "HE reconciled IN THE BODY OF HIS FLESH through death" (Colossians 1:21, 22) how "HE ALONE" (Mark 6:47) could eternally be "the image of God" (2 Corinthians 4:4/ Colossians 1:15) even "the express image of HIS PERSON" (Hebrews 1:1-3) in which God created man. Jesus Christ being "the image of God", then Brethren you must understand that "God created man IN His own image, in the image of God created He him" (Genesis 1:26, 27), which is nothing different from saying the God created man in Jesus Christ, "for we are His workmanship, created in Christ Jesus" (Ephesians 2:10). That "Revelation of the Mystery, which was kept secret since the world began, but NOW IS made manifest" (Romans 16:25, 26) in our mortal flesh (2 Corinthians 4:10, 11) explains why and how "the FIRST man Adam was made a living soul; the LAST Adam WAS MADE a quickening Spirit" (1 Corinthians 15:45) even when Christ says, "a spirit hath not flesh and bones as ye see me have" (Luke 24:39). In that "body of His flesh" (Colossians 1:22), even "the flesh of the Son of Man" (John 6:53) we must abide and "trust in Him AT ALL TIMES" (Psalm 62:8) as "the FIRST and the LAST", who "FIRST BEING by interpretation King of Righteousness, and after that also KING OF SALEM, which IS [present tense], King of Peace, without father, without mother, without descent, having [present perfect] neither BEGINNING of days, nor END of life; but MADE LIKE UNTO THE SON OF GOD" (Hebrews 7:2, 3) as a timeless manifestation of "the flesh of the Son of Man" (John 6:53) as eternal "members of His body, and of His flesh, and of His bones" (Ephesians 5:30). When "Jesus Christ is the same yesterday, and today, and forever" (Hebrews 13:8) as "the beginning and the end" (Revelation 1:8), and says that "there should be time no longer" (10:6), then time did not and does not exist always, anymore than it will exist always. But God lives, and His name IS JESUS CHRIST. And he exist always, and bears record to HIS existence in Heaven as "the FATHER, the WORD, and the HOLY GHOST: and these THREE ARE ONE" (1 John 5:7).
