It's not really solar flares and it'll not last for years.
It's a 12000 years cycle. The Sun goes nova, like every star does. The whole ordeal lasts for 7 days.
That's the 7 days of creation the bible mentions.
>It is scary but survivable. Humans have existed on earth for many of these 12000 year cycles.
That's right, we are all survivors. It's in our DNA.
The Gods got really pissed when they realize that Noah had survived.
They thought he had no chance. But here we are.
