@Ireneus: "Earth is filled with provisions for all its inhabitants."
Perhaps as "late comers" onto the scene of humankind, it can feel a bit like a sustainable and inhabitable home. But one look back at the earlier civilizations makes you realize the continued peril the earliest humans went through in order to maintain their existence as a species.
We know that the human species could be anywhere from a hundred thousand years according to Francis Collins, the physician and geneticist who oversaw the Human Genome Project - to two hundred thousand years old, as put forth by Richard Dawkins. For how many millennia was infant mortality and death during childbirth positively rife? Micro organism diseases were rampant and incurable. Death caused by the now-preventable tooth decay? Innumerable. In fact, the concept of a grandparent didn't exist until perhaps 30,000 years ago since the life expectancy was so transient.
Factor in volcanos, earthquakes and drastic climate changes and you'd have to think twice about the globe being a hospitable environment for the human species. Sure, with the advancement of technology, science and medicine, we've made something more accommodating out of it. It's the reason I can communicate ideas with you right now in the comfort of a warm dining room while it's five degrees Celsius outside. It's the reason my seasonal cold hasn't needlessly turned into pneumonia thanks to the flu meds I have in the cupboard, which is conveniently stocked with food I don't need to risk my life hunting for in the wild.
I am interested in the three phases you speak of (creation, preservation, destruction). What do you understand the destruction phase to be?
By simply saying such cosmological occurrences (eg: stars having an explosive birth AND death, galaxy collision courses) "would never happen" because it's an undesirable pattern break for your deity of choice doesn't mean it won't happen. That just sounds more like wishful thinking in the face of physics and astronomy. I cannot command for tomorrow to be a heatwave here so I can go to the beach any more than you can command the sun to stop exhausting its supply of hydrogen so that your perception of an incorruptible deity remains untarnished.
