So, am I right that the first main reality was Earth-2, then New Earth Pre-Crisis, then Earth Prime after Flashpoint and nowadays a merged reality of New Earth and Earth Prime (referred to as Earth-0 or Prime Earth)?
No its Earth two, then Earth One, then New Earth, and now Prime Earth or Earth 0. Not to be confused w/ Earth 2, -2, 1, -1 or Earth Prime, -Prime
The first was Earth C-
What do you think?
