Names are important. It is difficult for us to conceive of things apart from their names. The many different names for God in the Bible describe and demonstrate His character.
If we had the tongues of angels, we could not praise God as He deserves to be praised. If we were born speaking praises and had breath to never cease, we could never adequately exalt His name in this life. If every rock could speak, it would praise God. If the stars could sing, their song would be in His honor. If the animals could write, their words would form new praises for their Creator. The very stones would praise Him if the need arose, and a thousand legions of angels would leap to do His will.
