Men before Elves??

[Carannillion]

The Elves are the firstborn of ME, and Men are the second, the Children of Ilúvatar. BUT, the so-called 'Woses', the wild forest-men of the Druadan forest in Anórien were - according to a certain statement made by their chieftain Ghân-buri-Ghân during the War of the Ring - before even the elves...

Ghân-buri-Ghân says to Theoden that his people is an ancient people, and that they saw the other men (or something like that, 'men' here being an issue of discussion) comeout of the water.

Questions:

1. Did Men come out of the water in the beginning, like the Elves?

2. If not, then Ghân-bu... refers to his people having seen the Elves rise from the water?!?!?!?

3. If Men also came from the water, where did the Woses come from, and what are they?

Taken from David Day's 'A Tolkien Bestiary':

WOSES In the War of the Ring a strange primitive folk named the Woses came to aid the Rohirrim and Dúnedain (...) lived in the ancient Forest of Druadan (...) they had lived as naked animals invisibly among the trees for many Ages and cared not for the company of other people. The Men of Gondor (...) believed that they were descended from the even more ancient Púkel-men.

Anyone??
