Final answer:
Equiano's account is still credible due to his firsthand experience and corroborating historical records.
Step-by-step explanation:
Equiano's account is still credible despite the uncertainty surrounding his origin. While it is possible that Equiano may not have been born in Africa and kidnapped, his firsthand experience and interactions with fellow Africans who had been enslaved provide valuable insights into the slave trade. Equiano's account aligns with historical records and other narratives, lending credibility to his story. For example, Equiano describes how Africans enslaved each other, the treatment of enslaved people, and the role of Europeans in the slave trade, which are corroborated by other historical sources.
