The Mayans apparently were in a league comparable to the Chaldeans and the Egyptians when it came to recognizing Celestial events.
I think that your extrapolation of Biblical comments regarding future events is in contradiction with Bible tenets.
In the Book of Enoch CHAPTER XCIII. found at
We are at the end of the 7th week where an apostate generation arise, and many shall be its deeds,
And all its deeds shall be apostate. And at its close shall be elected The elect righteous of the eternal plant of righteousness, To receive sevenfold instruction concerning all His creation.
Paul also said A/C will not be revealed until the great fall away happens. I think we are seeing an apostate generation arise right now, but the righteousness of the Church will be confirmed after the coming trial.
6 A senseless man does not know,
Nor does a fool understand this.
7 When the wicked spring up like grass,
And when all the workers of iniquity flourish,
It is that they may be destroyed forever.
10 Many sorrows shall be to the wicked;
But he who trusts in the LORD, mercy shall surround him.
11 Be glad in the LORD and rejoice, you righteous;
And shout for joy, all you upright in heart!
God is at work right now, He will perfect a perfect government for His people. For Jesus said, the Kingdom of heaven is a merchant who is looking for a pearl of great value, when he found it, he sells all he has and bought the field. God is that merchant. He has found the great pearl, it is the Church. He has sold everything to purchase us. You will see death and decay of civilizations and nations, but the Church will live on.
We must trust Him, that is the most important preparation we can do for what is to come. In the meantime, get out of debt of all kinds, take on His yoke.
3. And Enoch began to recount from the books and said:
‘I was born the seventh in the first week,
While judgement and righteousness still endured.
4. And after me there shall arise in the second week great wickedness,
And deceit shall have sprung up;
And in it there shall be the first end.
And in it a man shall be saved;
And after it is ended unrighteousness shall grow up,
And a law shall be made for the sinners.
5. And after that in the third week at its close
A man shall be elected as the plant of righteous judgement,
And his posterity shall become the plant of righteousness for evermore.
6. And after that in the fourth week, at its close,
Visions of the holy and righteous shall be seen,
And a law for all generations and an enclosure shall be made for them.
7. And after that in the fifth week, at its close,
The house of glory and dominion shall be built for ever. p. 133
8. And after that in the sixth week all who live in it shall be blinded,
And the hearts of all of them shall godlessly forsake wisdom.
And in it a man shall ascend;
And at its close the house of dominion shall be burnt with fire,
And the whole race of the chosen root shall be dispersed.
9. And after that in the seventh week shall an apostate generation arise,
And many shall be its deeds,
And all its deeds shall be apostate.
10. And at its close shall be elected
The elect righteous of the eternal plant of righteousness,
To receive sevenfold instruction concerning all His creation.
