Years ago, I heard a teaching about a race of pre-Adamic men, that is there were humans on earth before Genesis 1:2. However, since the Bible tells us of God's plan and purpose in "time past", "but now" and "ages to come" and each of these time frames only deal with the time since Adam; do the scriptures teach that there was a human race before Genesis 1:2?

(Genesis 1:1-2 KJV) In the beginning God created the heaven and the earth. {2} And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.

Something happened between verses 1 and 2 in order for the earth to be without form and void. This was God's judgement on Satan's rebellion, when Satan declared he will be like the most High. (Isaiah 14:14)

(Isaiah 45:18 KJV) For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else.

In contrast to Genesis 1:2, this verse says that the earth was not created in vain and that it was created to be inhabited. Isaiah 45:18 is one of the passages used to conclude there must have been humans on earth before Adam. However the context of Isaiah 45 is the 2nd coming of Christ not the time before Adam was created. The preceding verse speaks of Israel being saved in the Lord with an everlasting salvation.

(Isaiah 24:1 KJV) Behold, the LORD maketh the earth empty, and maketh it waste, and turneth it upside down, and scattereth abroad the inhabitants thereof.

Here we see that the LORD made the earth void, made it empty and wasted it. Here we see Genesis 1:2 terminology to discuss the condition of the earth after the 2nd coming of Christ.

(Jeremiah 4:23 KJV) I beheld the earth, and, lo, it was without form, and void; and the heavens, and they had no light.

Or "I looked at the earth and it was just like Genesis 1:2, without form and void." Again, the context is the 2nd coming of Christ. When Christ comes again it will be in judgment. His judgment will destroy the earth. "Without form and void" describes the condition of the earth after judgment, which is God's wrath poured out upon the satanic plan of evil at the 2nd coming of Christ just as it was at the beginning of Satan's rebellion.

Genesis 1:2 uses last day terminology at the beginning; pictures the 2nd coming of the LORD as a man of war when He comes back and ends the battle. The battle that was started is not resolved until the 2nd coming of Christ when He finishes what was started.

God created the earth with the battle in mind.

(Isaiah 46:10 KJV) Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:

If we keep the context of the scriptures, there is no real scriptural evidence of a "pre-Adamic man".
