Hi Maria,

Greetings to you!

LastModifiedDate is automatically updated when a user modifies a record. Please refer to the below links which might help you further.

That's what I though Maharajan.C but I'm being told that's not the case for Lightning.  My EA team is telling me that custom objects in Lightning no longer automatically create that field any longer.  

Thank you Khan for getting back to me but I think I may not have been clear enough.  I wasn't trying to find out if the "last modified date" field is auto updated when a record is last saved; but if the field is automatically CREATED when a new object is created.  

It seems as though this is still an open issue; however, I created a new object in LEX and it does NOT contain the standard system field "Last Modified Date" or "Last Modified By".
