A Puzzle within an Enigma within a Cornflake Packet

Can anyone help me with this one as its popped into my head on numerous occasions over the years but I am no further forward.

In D&C 93:29 reads: "Man was also in the beginning with God. Intelligence, or the light of truth, was not created or made, neither indeed can be."

Since you can't create intelligences that implies there is a finite amount of them. However if this were true then at some point all intelligences would have received a spiritual/physical body and the promise of an eternal increase would not be valid.

Can anyone give any insight into how there can be an infinite amount of intelligences whilst at the same time no new intelligences being created?
