Tolkien: Evolutionist or Creationist?

[Eggy]

ok i could have miss understood this, but did not Eru "create" the vala, and didnt he create arda and create the first born (and second born).
If i remember right a Vala created the dwarfs because he was bored waiting for the first born,
and didnt Melkor create the dragons(and other evil spirits) from his own mallace.

in none of my readings of tolkien have i heard much, if anything ,about evolution only creation
