The jury isn't in yet on the subject of life after death, which anthropologists can not answer. It's a matter of personal faith.
In the christian faith, nobody knows when the apocalypse will occur. The bible states this specifically, that no one knows the time. However there are biblical landmarks according to bible prophesy:
Item 1
The nation of Israel must be reborn first, and all the world will be against it.
Item 2
Ezekiel Chapter 38
1 And the word of the LORD came unto me, saying,
2 Son of man, set thy face against Gog, the land of Magog, the chief prince of Meshech and Tubal, and prophesy against him,
Magog Gen 10:2, Eze 39:6, Rev 20:8
3 And say, Thus saith the Lord GOD; Behold, I am against thee, O Gog, the chief prince of Meshech and Tubal:
Gog Eze 39:1, Rev 20:8
The word derivations apply to eastern and western halves of former republic of USSR.
4 And I will turn thee back, and put hooks into thy jaws, and I will bring thee forth, and all thine army, horses and horsemen, all of them clothed with all sorts of armour, even a great company with bucklers and shields, all of them handling swords:
5 Persia, Ethiopia, and Libya with them; all of them with shield and helmet:
Persia is a united Iraq and Iran. The implication is an arab alliance.
6 Gomer, and all his bands; the house of Togarmah of the north quarters, and all his bands: and many people with thee.
Gomer is associated with the European continent.
7 Be thou prepared, and prepare for thyself, thou, and all thy company that are assembled unto thee, and be thou a guard unto them.
Item 3
An eastern army is mentioned that will cross the Euphrates with an army of 200 million to do battle at the valley of Armageddon.
12 And the sixth angel poured out his vial upon the great river Euphrates; and the water thereof was dried up, that the way of the kings of the east might be prepared.
Napoleon once visited the valley of armageddos and said it was the perfect spot for a battle of that magnitude.
It is surmised that only China is capable of assembling an army that size.
Item 4
Some form of a european alliance with 10 members is mentioned as a key player:
Revelation 13:1 And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.
Item 5
There is more in the book of Daniel.
