A lot of people flippantly use the terminology; the end of the world, this World/ Earth is never going to END, there are going to be end time wars, and much destruction and death.
Matthew 28:20…”Lo, I am with you always, even to the end of the AGE. It’s always about the end of one age and the beginning of another, 2nd Peter 3( in its entirety) does a fantastic job of explaining the three Earth ages. We are currently in the Second one, and it is winding down with all the coming trouble, which will lead to the Second Coming of Christ.
The third Earth age is the Millennium, the thousand year reign of Christ from the New Jerusalem. I believe we are fast approaching the Tribulation or Daniel’s 70th week (I think that’s right) all prophesied.
So when people say the end of the world is coming, just understand that it’s not going to END, however the AGE will end.
IT is commonly believed, or at least one school of thought is, that this second Earth age that we’re currently in…. at least modern day history, leading into recorded history of man… the story of Adam and Eve, and dealing with the nation of Israel… began around 4003 B.C. what happened prior to that would encompass at least 1 Earth age, spanning an unknowable amount of years… maybe Aeons.
