Kepler-96 is an active solar-type star harbouring a Super-Earth planet inclose orbit. Its age of 2.3 Gyr is the same as the Sun when there was aconsiderable increase of oxygen in Earth's atmosphere due to micro-organismsliving in the ocean. We present the analysis of superflares seen on the transitlightcurves of Kepler-96b. The model used here simulates the planetary transitin a flaring star. By fitting the observational data with this model, it ispossible to infer the physical properties of the flares, such as their durationand the energy released. We found 3 flares within the energy range ofsuperflares, where the biggest superflare observed was found to have an energyof 1.81$\times$10$^{35}$ ergs. The goal is to analyse the biological impact ofthese superflares on a hypothetical Earth in the habitable zone of Kepler-96assuming this planet has protection via different scenarios: an Archean andPresent-day atmospheres. Also, we compute the attenuation of the flare UVradiation through an Archean ocean. The conclusion is that considering theincrease in the UV flux by the strongest superflare emission, {\it E. Coli} and{\it D. Radiodurans} could survive on the surface of the planet only if therewas an ozone layer present on the planet atmosphere. However, they could escapefrom the hazardous UV effects at a depth of 28m and 12m below the oceansurface, respectively. For smaller superflares contribution, {\it D.Radiodurans} could survive in the surface even in an Archean atmosphere with noozone.
