If there has been Billions of Years of Earth History – is it more likely that life has survived Mega-Solar Flares or maybe that’s evidence that life was Created more recently!
“COULD the Sun send out a monstrous flare powerful enough to melt the ice on Jupiter’s moons, destroy much of Earth’s ozone layer and obliterate all our satellites? It’s possible, say astronomers who have studied other Sun-like stars in our Galaxy, which seem to produce enormous “superflares” about once a century. They are baffled by the fact that there are no records of similar solar explosions.”
