Final answer:
The basis and evidence for King Tut's curse come from historical records and scientific research.
Step-by-step explanation:
The basis and evidence for King Tut's curse come from a combination of historical records and scientific research.
Historical records show that Lord Carnarvon, the financial backer of the Tutankhamun excavation, died shortly after the tomb was opened. This led to sensationalized newspaper articles about a curse on the tomb.
Scientific research has also played a role in understanding the curse. Studies conducted on the mummies and artifacts from King Tutankhamun's tomb have identified the presence of harmful bacteria and toxins, which could have contributed to the deaths of some individuals associated with the excavation.
