Birth of an Island

Fir

First Earth was all rock, debris circling the sun that coalesced into a planet.

Then comets came, bringing water, covering much of the land (all? not sure).

Then volcanoes rose up from the ocean bottoms, creating land.

As plates moved, land masses moved and accreted onto larger landmasses.  Continents were born.

Here's a photo of the birth of an island:
