AEServer explained
MacBook Air
Im not debating or disbelieve this answer... but if this server has been here for decades then why does it tell me this file or "server" is a file that was created (and compressed...) over a year after this computer was released and then sent to a folder where it remains the only file...
It is a bit paranoid to question this, but I have had one other MacBook (2014- the ex broke it :() and it never did the weird things this one does. It also didn't do it as often. This computer freezes, display pixelizes, files delete on their own, files move on their own and duplicate, also these kinds of files all of a sudden appear after (or sometimes before) these problems occur and they scatter themselves among the computer in folders I cannot see normally or ever access... Its just weird for these necessary, normal, traditional (whatever) files and "servers" to appear well after I first set the computer up. Plus they take up an ungodly amounts of space. My "others" storage is over 10GB...
