EVE. Not sure where the "EvE" usage originated, although there is a running joke that it's "Everyone vs Everyone". Also not sure why it's all-caps.

However, generally the name originates in the game's backstory with the "EVE Gate" which was a now-expired wormhole that appeared somewhere in Earth's proximity and lead to "New Eden" which is the cluster where the game takes place.
