Cosmology: Earth in goldylocks zone; dangerous (Introduction)

A planet must be in the goldylocks zone if life is to start. But in that zone the space around the earth has a WEATHER produced by the sun that is very unhospitable to life and inanimate electronics. On Earth we are protected by ozone layer, the atmosphere itself and the magnetic field around the Earth caused by the nickel-iron core of the Earth, liquid and sloshing around inside.

We don't have enough information. Claims like that are like the sheep joke I love:-An astronomer, a physicist and a mathematician decide to vacation in Scotland. In the countryside, suddenly the astronomer called out, "By jove, a black sheep! All sheep in Scotland must be black!"-The physicist replied, "No, statistically speaking only some sheep in Scotland are black!"-The mathematician looked skyward for a moment than intoned "In Scotland, there exists a field, and in the field, exists a sheep, of which at least one side is black!"-You're being an astronomer, David!

\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
