Several people over the years have written to The Refiner's Fire asking for an explanation about science and the age of the earth, so, we ask that you first check out our article, Science versus the Bible. Concerning the time it takes for wood to petrify. please read Does it take millions of years to petrify wood?
Concering the time of man on earth, we learn the following from Talmud (the "Oral Torah" - which is commentary on the first five books of the Bible):
Sanhedrin, Babylonian Talmud p. 97 a.: Rabbi Kattinna said: Six thousand years shall the world exist, and one [thousand, the seventh], it shall be desolate, as it is written, And the Lord alone shall be exalted in that day. [quotation from Isaiah chapter 2 verse 11]. Rabbi Abaye said: It will be desolate two thousand as it is said, After two days will he revive us: in the third day, he will raise us up, and we shall live in his sight [quoting from the prophet Hosea chapter 6 verse 2]. Two days meaning two thousand years according to Psalms 90 verse 4.
As of this writing, we are in the Hebrew calendar year of 5780 - not really that far from the year 6000 - especially, given the fact that that some Hebrew calendar and Bible experts are suggesting there might be be some mathematical miscalculations resulting in "missing years" in the Bible.
What we can be sure of, however, is this: Judging from all the events going on in the world and specifically, in the Middle East with Israel at the center, we can be sure that Yeshua's Second Coming isn't that far off! (We know of one Hebrew and Aramaic scholar who suggests that Yeshua's Second Coming could be as close as Rosh Hashana, 2030!)
What we must realize is, YHWH's Feasts - His Appointed Times - reflect many major biblical events. Yeshua has so far fulfilled the first four of the seven and the next one to be fulfilled is Rosh Hashana, the Feast of Trumpets - the day when YHWH calls His people together....Sounds an awful lot like the "rapture" will occur on a Feast of Trumpets....
The above concepts are very deep and requires us to have some understanding of God from the Hebrew, as opposed to the Greek mindset.
