Now that I think abuot it, before the two huge lamps that Melkor knocks over, was there light then? what about after he knocks the lamps over, back to darkness?
No, Tolkien abandoned that mythic beginning. He wrote about how the myths surrounding the beginnings of Creation are essentially garbled in The Silmarillion (as enough of it had leaked through in The Lord of the Rings). He had abandoned a great deal of the ideas that had originally been presented in The Lost Tales and The Lays of Beleriand. This comes from The Peoples of Middle-Earth.
- Ea is the Universe/Creation. The Sun, the Moon, the constellation of Earendil, they all existed from the start.
- There was no Flat Earth. It was always globed and it appearing as flat was the confusion of the Numenoreans (some of whom may have realised it was a globe much earlier).
- The Elves did awaken to starlight. They awoke at night and saw the dawn the next morning.
- The Two Trees had captured the early light of the Sun and Moon in them, but they were never the source of all light of Ea.
- Men awoke not very long after the Elves. The fact that the Vala Orome did not encounter Men is that they were nowhere near Cuivienen. They most certainly were awake by the time the Eldar had crossed into Beleriand.
- Men, not Elves, were the race corrupted and twisted into Orcs by Melkor.
