Golden, Silver, Bronze/Copper eras in comics are just common designations for the different styles that the comic industry developed in time. As it doesn't involve the characters directly, that "first appearance" is irrelevant; but I think that question was already answered in the forums.

The "Earth" designations we use here, are considered important because the company (DC) changed something in the character's history and that alone is more important than the eras of comics; at least for us.
