Bro. Blume may have mentioned this but another verse used to support the "pre-Adamic theory, is
Gen 1:28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth. Replenish means to RE-fill. To make full AGAIN.
