What was created on the first day?

Answer From Source: Skies, Land, Water, and Light (Genesis 1:1-5)

Additional Comments: You could also say that Yahweh created the "separation between light and darkness", but the original intent of this question was more simple focused on what "things" were created.

Because, the land was probably under the water! We don't see the waters gathered together until the third day.
