Trying to be polite....... how on Earth (I nearly said "in Heavens name"!) do you claim God is supposed to have told Man what to write?

The whole thing is a collection of ancient myths and stories all cobbled together to explain what, at the time was inexplicable and to suit those with (at that time) a vested interest in maintaining a form of control over the population.

When people say "With the greatest respect" what they really want to say is completely lacking in respect and mostly unprintable!

The Sun will definitely die as I (and Pete) said. It will gradually consume all its Hydrogen and start burning Helium. The Sun will expand and get hotter and hotter and eventually the Earth will have all its atmosphere vapourised and the water all boiled off before the whole Planet fries to a cinder.

As that's a few billion years away yet, I won't worry about it.
