Today this theory has little support. Egyptologists such as Toby Wilkinson, I. E. S. Edwards, and Winifred Needler deny the 'usurping theory', because Semerkhet's name is mentioned on stone vessel inscriptions along with those of Den, Adjib, and Qa'a. The objects were found in the underground galleries beneath the Pyramid of Djoser at Saqqara. The inscriptions show that king Qa'a, immediate successor of Semerkhet and sponsor of the vessels, accepted Semerkhet as a rightful ancestor and heir to the throne. Furthermore, the Egyptologists point out that nearly every king of First Dynasty had the habit of taking special vessels (so-called 'anniversary vessels') from their predecessor's tomb and then replacing their predecessor's name with their own. Semerkhet not only confiscated Adjib's vessels, in his tomb several artefacts from the necropolis of queen Meritneith and king Den also were found. The lack of any high official's tomb at Saqqara might be explained by the rather short reign of Semerkhet. It seems that the only known official of Semerkhet, Henu-Ka, had survived his king: His name appears on ivory tags from Semerkhet's and Qaa's tomb.
