The problem with the Day Age Theory is that Genesis says there is a night and day attached to the numberng of the days. If you are to assume the days are speaking of long periods of time, then we must also assume the night and day are long periods of time, too. Meaning, the night period time would be for thousands of years. This would be a problem because the plant life thrives on the sun along with the animals who depend on that plant life (in order to survive).
Also, Adam is a literal person: Adam is not metaphorical and he is the first man within the creation. Just look at the geneology of Jesus Christ in Luke chapter 3. For it traces Christ's genealogical line thru Mary all the way back to Adam.
Furthermore, Jesus says,
4 "And he answered and said unto them, Have ye not read, that he which made
them at the beginning made them male and female,
5 And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?
6 Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder. (Matthew 19:4-6).
Why does the Lord say they are one flesh? Because God took a rib out of Adam's side and made Eve.
And Eve is called the mother of all living (Genesis 3:20).
Now, if you believe there was a Pre-Adamic race based on the words "old world" in 2 Peter 2:5: Well, this would be ignoring the context that it is talking about the saving of Noah in that very same verse.
Also, Jeremiah 4:23-27 does not support a Pre-Adamic race, either. Here is what it says,
"I looked at the earth. It was empty; there was nothing on it. I looked at the sky, and its light was gone. I looked at the mountains, and... they trembled, and all the hills moved lightly to and fro. I looked, but there were no people. All the birds of the sky had flown away. I looked, and the fruitful land had become a desert. All its cities were broken down at the presence of the LORD, and by his fierce anger. This is what the LORD says: The whole earth will be ruined, although I will not destroy it completely." (
Jeremiah 4:23 ERV,
Jeremiah 4:24 AMP,
Jeremiah 4:25 ERV,
Jeremiah 4:26a ISV,
Jeremiah 4:26b WEB,
Jeremiah 4:27 GWT).
But what is it talking about really? It is talking about the utter destruction of this world after Jesus returns (And all the nations come up against Him).
Revelation 16:16 and
Revelation 16:14
And
He gathered them together into a place called
in the Hebrew tongue
Armageddon. To gather them to the battle of that great day of God Almighty.

Revelation 19:17-18 and
Revelation 19:14
And I saw an angel standing in the sun; and he cried with a loud voice, saying
"
To all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God; That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great."
And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
