Thanks for starting these topics Minimus I really enjoy them,
It is all JW BS, all the evidence says there will be no God induced big "A" event. After taking a lot of classes at University which presented an incredable amout of hard evidence that the Earth is immensly old and was not formed or shaped by any of the events recorded in the Bible I think it's a safe bet that the Watch Tower Society doesn't have the foggiest notion even about the past let alone the future. The WTS has NEVER gotten one thing right yet as far as predictions go so I'm not the least bit worried about the END as they see it. We do know however, that there have been some huge events over billions of years which have caused the extinction of 99% of all living things on the planet which quite probably were caused by bolide (large astroid) impacts. The Earth is enormous however, so life has always managed to recover despite all the climate changes and impacts so I think we will have plenty of time to spread across space bringing earthly life forms to the rest of the uninhabited Universe and hopefully sharing it with what ever extra terrestrial life forms we may encounter. Eventually the Earth will be destroyed by the natural forces which created it but it will be a looong time in the future and hopefully by then our decendants will have many options for habitation far away from danger.
