I'm trying to edit a project by deleting some objects directly from the scene view, however the objects are returning even though I'm saving it. I'm i deleting the objects the right way?
Make sure your game isn't running when you're deleting your game... Also, try re-saving in a new location.
If you mean while it's running, look up the Destroy() command.
Also make sure that no script is generating new objects at runtime, if the problem you're stating is related to objects you see while the game is running!
