Have you examined the "mummy" before speaking? Or you think you don't need to do that because of your degree ?
No need to. The process of mummification is well documented and has been for centuries. Also the process of peer-reviews does not require me to look at the body itself rather just look at the data provided. Your provided data from a non-expert contradicts established findings by the overwhelming majority of experts. So it easy for me to conclude that your source was wrong due to his own ignorance of mummification along with past and present data ofRamesses II available. He is the Pharaoh linked to the Exodus.

The life of Ramesse II is also one of the most documented mummies in Egyptology. We know how he died, it wasn't due to drowning. He died at the age of 90, crippled by arthritis and could only walk with aid of a cane.

In Bucaille's book he writes about Merneptah not Ramesses II. However the video you linked shows pictures of Ramesses II. So the creator of your video didn't even know enough that they had the wrong Pharaoh. So already he is a minority as Merneptah is not the person linked with the Exodus. Merneptah ruled post Exodus as the Merneptah Steele is the first inscription talking about the Israelites in Canaan as a people. With the Steele the inscription depicts a military campaign into Canaan and the a victory over the Israelites. So already there were a people identified as Israelites in Canaan with no links to previous or mention of previous Hebrew slaves which the Egyptian would know if in fact the Exodus happened, which it did not. Merneptah ruled for 10 years yet the Exodus cover a period of 40 years. So the Exodus could not have happened during his reign if he fought the same slaves of the Exodus.

There is also the conflict of interest with Bucaille. He was the personal physician King Faisal of Saudi Arabia and Anwar Sadat. This position is the only reason he was granted access to the mummy as he is a non-expert. His work was financed by both parties as was his book. Him and his work is not even considered in the sphere of Egyptology or archaeology but rather as religious apologetic. As my sources above lay out his work is only his opinion, that of a non-expert, and is not even considered by experts in their own work. Bucaille has no creditability in any field outside his own as a medical doctor. He is not a forensic Archaeologist, Egyptology, he doesn't even had 1 credit in any related field.
I think I have made my case and shown yours to be confirmation bias in favour of your religion. Of course you are free to believe what you want. However it is an unsupported hypothesis dismissed within the field itself and by experts in the field. Yes a degree does granted me the right to review work within my field of expertise and related fields, it is called peer-review. As I said before his own ignorance of mummification caused him to reach the wrong conclusion as does his conflict of interest during a period of Pan-Arabism which both Faisal and Sadat were leading figures of.
