I've discovered people arguing that the "Aryans" descended from Ham.

Chariots had been used in Egypt as far back as the Old Kingdom.

This is now known thanks to discoveries made in 2013.

In ancient Egyptian society chariotry stood as an independent unit in the King’s military force. Chariots are thought to have been first used as a weapon in Egypt by the Hyksos^[1] in the 16th century BC, though investigation of materials long held in the Tahrir Square Egyptian Museum has potentially revealed the presence of chariots as early as the Old Kingdom (c. 2686–2181 BC).^[2] The Egyptians developed their own design of the chariot.

Much past discussion of when in Egyptian History certain Biblical events could have happened were based on the long held assumption that there were no Chariots in Egypt till the Hyksos period.  But we now know otherwise.  I wish I'd known about this sooner, being made in 2013 it predates my starting this Blog, I could have opened with it.

I'm still reevaluating just how much of my past Revised Chronology speculations I still agree with.  But for now this is an enlightening discovery either way.
