I've been following this in the news and am glad Still Waters posted it. I had meant to but never got around to it. This is a very exciting find and a great example of legitimate archaeological and Egyptological work. To me it's a reminder that the real world is fascinating enough and how continued pursuits in Egyptology bring more and more knowledge to our understanding of pharaonic Egypt. Aliens and Atlanteans and other woo-woo stuff need not be considered.
Whether the boat at Abu Rawash is actually the oldest remains to be seen. Unless I missed it the article doesn't mention the fourteen
Abydos boats. These were discovered in the late 1980s by one of David O'Connor's teams and were excavated in 1991. They were found alongside a large funerary structure known as the Western Mastaba. Unfortunately it has not been possible as of yet to assign the Western Mastaba or the boats to any specific king, but it's been established that these boats also date to Dynasty 1. This means the Abydos boats are around the same age as Den's found at Abu Rawash—5,000 years old.
I suppose the question is, which came first, the Abydos boats or the Abu Rawash boat? We might never know. Den reigned in the middle of Dynasty 1, so it's difficult to say with any certainty.
It's unusual that such a boat was found at Abu Rawash, which would've been a very remote spot and a considerable distance from the Nile in Dynasty 1. Not that the Abydos boats themselves are exactly right next to the river, but Abydos would've been a bustling and well-established site even in Dynasty 1. The article is correct that Den was buried at Abydos, along with the other kings of that dynasty, and no evidence for a cenotaph is known for him at Abu Rawash. It's possible, then, that the boat was buried for a nobleman in the court of Den—the boat may be attributed to Den but might not necessarily have been buried for him. There is some precedent for this in other noblemen's burials of the Early Dynastic Period.
Whatever the case may be, it's a fascinating discovery. Makes you wonder what archaeologists will find next.
And to questionmark, remember that many boat pits never contained actual boats. So the ones with boats were meant for that purpose, while those without boats were actually for diamond saws.
