"To solve the mystery surrounding this skull, researchers utilize comparisons with other skulls that have similar characteristics, particularly those that also exhibit circular-shaped holes in the head."

"A person from the future, carrying a firearm, travels back to the past and is involved in a time-travel hunting expedition," The Shields Gazette stated in its radical theory. Furthermore, there is an unreasonable theory suggesting that the hole may have been caused by small meteoroid fragments."

Not only that, from the Bad Archaeology website emerged an alternative theory that rejects the existence of a wound on the right side of the skull. Although without providing any explanation or concrete evidence, the theory states that the bullet-like hole is actually caused by "pathological passage, not traumatic lesions, which arise due to infection in the soft tissues above it."
