In S04 of Lucifer Eve arrives to Earth.
She seems to be extremely well versed in how contemporary Earth works, despite being in Heaven since ever.
She mentions that she asked questions about life on Earth by people "going up" and realizing life on Earth is fun, but this is not enough to understand how to deal with our world (she knows about planes, about the post office, teeth brushes, how to order in a bar (where does she have money from?), etc.
How does she manage to get by?
