To doubt Temple's thesis without knowing more about these cosmologies and etymologies is bad science. If there is doubt (and I have my own suspicions), it behooves the researcher to find solutions, rather than denigrate the person.
What I'm also curious about is Hancock and Bauval's book "The Message of the Sphinx"; due to Temple's hypothesis that the Sphinx is not a lion-man, but is possibly a vandalized statue of Anubis! The conflict between Hancock and Bauval's and Temple's theories is that the former seems to have good astronomical evidence that the Sphinx and the Giza complex are aligned to Leo-oriented stellar events...if the star clock is wound back in time 10,000 years (this time period would also explain the water erosion at the Sphinx). Temple's theory doesn't go back 10,000 years, but remains in the orthodox view that the pyramid complex is from 2500 BC. Temple's theory focuses on the "Dog-Star" Sirius, rather than the constellation Leo.
So, there are three competing theories - the orthodox, the anubine and the leonine. I'm not an Egyptologist, an archeo-astronomer, an archeologist, an etymologist, or an archeo-engineer but it seems that all these disciplines would be required to find more cohesive evidence that lays to rest theories that aren't "the best fit".
