No one got it right.
The universe as a whole is created and destroyed in four billion-year cycles (one kalpa each). We're currently in the middle of the cycle, ie the universe was created two billion years ago. And Brahma the creator god lives for a longer time than that - three hundred trillion years - and we're halfway through that period as well.
Of course all these numbers are entirely "beautiful" mathematical constructions, and don't have any actual basis in observations or reality.
