QUES: Buddhists believe Gautama Buddha was the first to achieve enlightenment in this Buddha era and is therefore credited with the establishment of Buddhism. A Buddha era is the stretch of history during which people remember and practice the teachings of the earliest known Buddha. This Buddha era will end when all the knowledge, evidence and teachings of Gautama Buddha have vanished.
