According to the Laravel framework's documentation: If you are listening for many events on a given model, you may use observers to group all of your listeners into a single class. Observers classes have method names which reflect the Eloquent events you wish to listen for.
Simple Difference Between Events and ObserversObservers are basically predefined events that happen only on Eloquent Models (creating a record, updating a record, deleting, etc). Events are generic, aren't predefined, and can be used anywhere, not just in models.
You may consider jobs as something that needs to be executed in order for your application to work properly. Events are mostly side effects/results of those actions - while important and useful, they play a secondary role.
Laravel Observers are used to group event listeners for a model eloquent. Laravel Observers will listener event for model eloquent method like create, update and delete. Retrieved: after a record has been retrieved. Creating: before a record has been created.
Observers and events do not do the same thing at all.
Simple Difference
Observers are basically predefined events that happen only on Eloquent Models (creating a record, updating a record, deleting, etc). Events are generic, aren't predefined, and can be used anywhere, not just in models.
Observers:
An observer watches for specific things that happen within eloquent such as saving, saved, deleting, deleted (there are more but you should get the point). Observers are specifically bound to a model.
Events:
Events are actions that are driven by whatever the programmer wants. If you want to fire an event when somebody loads a page, you can do that. Unlike observers events can also be queue, and ran via laravel's cron heartbeat. Events are programmer defined effectively. They give you the ability to handle actions that you would not want a user to wait for (example being the purchase of a pod cast)
The documentation does a very good job covering these.
