12 mins in and the "evidence" put forth suggests that tuthmose I built it, with Hatshepsut finishing it (phase 2), this would also be supported by tuthmose + Hatshepsut in reliefs together (note how they're the same size, typically female royalty was almost always drawn or carved much smaller than pharohs, possibly suggesting her elevated status, or her own attempt at such elevation if those reliefs are done after the build was done, if they're done during construction then that would suggest tuthmose I elevated Hatshepsut!)
