Hello I have a question about mummies. I have been arguing with people in my university about the reason why mummies, after being mummified could still have skin, hair, etc... after being found thousands of years later. I have read many different arguments about how or why this could have occurred. The answer I found most commonly and that makes most sense to me is that ancient Egyptians would use salt, which would take out the moisture away from the body, therefore maintaining the features of the body for many years to come. nevertheless, I have professors and books that state that humanity is still uncertain of what was used in keeping the mummies preserved. So I guess my question to you would be, do we as humans know for certain what helped preserve the mummies or is it just educated guesses that archaeologists and scientists assume?

Thank you
