This was actually accomplished when Elves were introduced into the tale. The Valar had the Elves come to Aman where Melkor was imprisoned for three Ages. Also, the Maiar were all bound to Eä who entered it. There was no heaven. Melkor reigned in the North of Beleriand. Aman was set west of Beleriand in the sea. In Manwë's words:

I'm not sure about the Aman - Eden comparison. It was never meant to be a home to Men, but rather of the Elves [who it seems you are assuming are like the angels of the Bible; I'd say, if I were to have a pick, that it was the Maiar who were like angels] and the Maiar, and they built it and fortified it as a defense against Melkor.
