When life originated on Earth is still a hotly debated in science. The evidence available was from already fairly complex bacteria. These bacteria must have evolved from more simple life forms but little or no evidence exists to confirm this.
The first conclusive evidence for life comes from the Neoarchean Era(2,800 - 2,500Ma) about 2.74 billion years ago.
However there is evidence that there was bacteria alive in the Paleoarchean Era(3,600 - 3,200Ma) about 3.45 billion years ago.
