and if it's not in either of those, then, uh... make one?
This part, at least, shouldn't be possible, because the core vanilla breed egglayer entries are agents and are in the folder. So it definitely does exist from the start (and deleting it afaik would render the game unplayable).
I second what Lurhstaap said, the only place I've ever seen My Agents is in documents -> Creatures -> Docking Station or in GoG Games -> Creatures Exodus -> Docking Station.
You can also do a computer search at the harddrive-wide level for "My Agents" but the result will likely be in one of those two places, unless you custom installed your game someplace weird.
