A: Created and Created By field are the system fields, which cannot be edited.
System captures this information. You can have this fields in view form. But on Edit Form you cannot add these field. These are read only fields.
All System fields or the custom fields which are marked as read only cannot be found on edit or new page.
Note: Even Modified and Modified By fields are also read only and cannot be made available on New/Edit form.
