Ankh (examples)
A few examples of early dynasty period Ankh symbols (see: cross), the earliest of which, e.g. ankh of king Hor-Aha (c.3050), middle left, or Hor-Djet (c.2980BC), middle right, seem to have two legs, which in 2800BC were bent together into a one combined shape, far right.
In symbols, Ankh, the forerunner to the Coptic ankh (Coptic cross), which became the Christian cross, is a symbol of inexact origin, the circle or looped part, generally viewed as being the sun (or sun disc), the other undefined, give or take specific theories, e.g. southern crux theory, legs and arms of Khepri (scarab) rolling (or flying) the sun disc through the sky, among others.

Budge
In 1904, Wallis Budge stated that the circle amulet "Circle amulet", oft-seen been held by various Egyptian gods, asserted by some to be "related" to the ankh, was the "emblem of the sun's path in the heavens and of eternity". [1]

Petrie | Loin girdle
In 1905, Flinders Petrie suppositioned that the ankh was a male loin girdle worn around the waste. (Ѻ)

Southern Crux | Ankh
In 2006, Peter Joseph, in his viral Zeitgeist, asserted the view, based on Dorothy Murdock (1999), and others, that the Ankh, in the context of astro-theology, is symbolic of the re-birth of the sun on the or at the position of the star constellation of the southern crux. This southern crux sun ankh model, however, does not seem to align with the older ankh with two legs depictions.

Khepri | Ankh
In 2016, Libb Thims was loosely conjecturing following is an image of the conjecture that the two-legged ankh (c.2980BC) is representative of the Khepri-Ra god (dung beetle rolling scarab) flying or rolling the new-born sun into the sky, the arms and legs of the beetle being the two arms and two legs of the Ankh of 1st dynasty Egypt:
