Is it permissible to use the name "Athena" as a username on the internet, knowing that it is the name of an ancient Greek goddess?

The name "Athens" is one of the names of the alleged Greek goddesses. Therefore, it is not permissible for Muslims to use it to name a person, a city, or anything else, because it involves promoting a symbol of disbelief (kufr). As for the capital of Greece being named after it, that is the concern of its people. It is permissible for a Muslim to use the name when narrating or describing, but not as an affirmation.
