Can anyone tell me if this is the original Front door for a 1700's Georgian Colonial in Pennsylvania? How can we tell what kind of wood the doors are made from?

Currently the exterior is painted white and the interior is painted brown.
The long panel is from the side lights.
The rectangular white panel is a close up of the exterior of the door panel.
The brown door photo is the interior door with a view of the transom and side lights.

If these are not original, what style of door was most popular during that time period for a Georgian Colonial in Pennsylvania?
