Were there wheels before the stone pillars of the Osireion were created; and if so how how were those stonemasonry methods lost?

The Great Pyramid Grand Gallery locks have spots for things that roll or that rope rigging may have pulled around.

Hydrological engineering pyramid construction methods:
Herodotus, Strabo, Edward J. Kunkel "The Pharaohs Pump", Steven Meyers, Chris Massey

Herodotus > Life > Early Travels: https://en.wikipedia.org/wiki/Herodotus#Early_travels

> For this, they said, the ten years were spent, and for the
underground chambers on the hill upon which the pyramids stand, which he caused to be made as sepulchral chambers for himself in an island,
having conducted thither a channel from the Nile.

Sounds like the same story for the Osireion, according to Strabo.

Ancient megalithic Geopolymer masonry made with electrodes and [Lingam,] electricity is apparently lost to modern day as well.

FWIU, in the Great Pyramid, there were/are copper rods in the shafts out from the King's Chamber, and the conductive gold at the top of the pyramid was added after construction over top of a perhaps more ancient well shaft (that is not as geomagnetically-aligned) that may have been a hydraulic/hydrologic water tunnel given the water erosion in the subterranean chamber.

Fairly,
Demonstrate moving and then placing an 80 ton granite stone with ancient materials and tools: copper, gold, limestone, granite, probably fulgurite (sand glass due to lightning) and/or volcanic glass, obsidian, grain dust, papyrus rope, papyrus boats, barges, [variable buoyancy] crane machines, masonry forms and jigs, chemistry in jars, large sceptre tuning forks, sand, porous cliffs by the sea

What are the dates on the outer structure, and on the oldest largest object within the structure?

Well: Cyprus (8400 BC),

Wheel: Pillars, Potter's wheel (4500–3300 BCE), chariot (2200–1550 BCE), stone saw

Gears: Antikythera (200 BC), Watchmaking c. 1300 AD

But the boat, and things that float due to ballast or no; how old is that?

Aliens of similar height, from the tunnel and stair heights and sarcophagi.

Such as the [presumed] Sarcophagus of Senusret II - which has a pyramid built around it with perhaps newer and less precise masonry methods - which one might've hoped had contained instructions on how to produce spec granite at those tolerances back then; [1]

There is little evidence of advanced mechanical masonry tools at the time, except for the remaining megalithic stonework that later cultures built upon.

FWIU there are only a few examples of circular polishing, and the core drilling method leaves different signatures than known methods in modern day.
