Look at prophecy from a differnt perspective.

What if these people were not seeing the future but just had access to informatation that has been lost over the ages.

If a person knew of a cyclical cosmic event it may seem like they are telling the future but in all reality just had inside information.

KOLBRIN BIBLE

Manuscripts 3:6
The people will scatter in madness. They will hear the trumpet and battle-cry of the DESTROYER and will seek refuge within dens in the Earth. Terror will eat away their hearts, and their courage will flow from them like water from a broken pitcher. They will be eaten up in the flames of wrath and consumed by the breath of the DESTROYER.

Creation 4:6
THE STAR grew and waxed to a great brightness and was awesome to behold. IT PUT FORTH HORNS and sang, being unlike any other ever seen.

MOTHER SHIPTON POEM

For storms will rage and oceans roar
When Gabriel stands on sea and shore
And as he blows his wondrous horn
Old worlds die and new be born.

Nostradamus

C2-Q41
The great star will burn for seven days,
The cloud will cause two suns to appear:
The big mastiff will howl all night
When the great pontiff will change country.

THE BIBLE

30"At that time the sign of the Son of Man will appear in the sky, and all the nations of the earth will mourn. They will see the Son of Man coming on the clouds of the sky, with power and great glory. 31And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other.
