The word "samsara" is available to be said from the Vedas, whose author is the great sage "Vedavyasa." He gave us the word "samsara". So He is the authority. Fortunately therefore we don't need to "guess" what is the cause of samsara.
Srila Vyasadeva teaches i us in Bhagavad-gita, that "samsara" began with our rebellion against Godhead, from jealousy of God. We wanted to be God and so Krishna gave us a chance to make believe we are Him.
This, according to the person who gave us the word "samsara", is how it began as explained in detail within Bhagavad-gita.

The calendar is intended to mark the number of years since the death of King Herod the Great. The Roman abbot Dionysus Exiguus devised the new Christian calendar in 533. He knew that it was impossible to say when Jesus was born, but he knew, or thought he knew, when Herod died. So, he chose to begin his Christian calendar on the year of Herod's death, and he based this on the reign of the Roman emperor Augustus. Unaware that Augustus only adopted that name four years after his reign began, going by his birth name of Octavius until then, Exiguus commenced his calendar just 4 years too late.
