  Kepler-96 is an active solar-type star harbouring a Super-Earth planet in
close orbit. Its age of 2.3 Gyr is the same as the Sun when there was a
considerable increase of oxygen in Earth's atmosphere due to micro-organisms
living in the ocean. We present the analysis of superflares seen on the transit
lightcurves of Kepler-96b. The model used here simulates the planetary transit
in a flaring star. By fitting the observational data with this model, it is
possible to infer the physical properties of the flares, such as their duration
and the energy released. We found 3 flares within the energy range of
superflares, where the biggest superflare observed was found to have an energy
of 1.81$\times$10$^{35}$ ergs. The goal is to analyse the biological impact of
these superflares on a hypothetical Earth in the habitable zone of Kepler-96
assuming this planet has protection via different scenarios: an Archean and
Present-day atmospheres. Also, we compute the attenuation of the flare UV
radiation through an Archean ocean. The conclusion is that considering the
increase 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 there
was an ozone layer present on the planet atmosphere. However, they could escape
from the hazardous UV effects at a depth of 28m and 12m below the ocean
surface, respectively. For smaller superflares contribution, {\it D.
Radiodurans} could survive in the surface even in an Archean atmosphere with no
ozone.
