Earth's early organisms most likely used anaerobic respiration to break down glucose and generate energy. This is because, in the early conditions of Earth, there was little to no oxygen in the atmosphere, making aerobic respiration unfeasible. Anaerobic respiration allows organisms to generate energy without the need for oxygen.
Like modern organisms, the earth's early organisms also needed to break down glucose to generate the energy required for survival.
