In the flood Scriptures, the words “earth & heavens” can be local and not global. The can also mean the earth as a land orl and not glob and the heavens as the visible arch of the sky. The earth being round allows that it could have been referring to the heavens viable from the flood locale. I know how they read in the English, but observe the Hebrew definitions from the Strong’s Concordance:
19 And the waters prevailed exceedingly upon the earth; and all the high hills, that were under the whole heaven , were covered. (KJV)
Definitions for above:
earth: Hebrew word #776 'erets (eh'-rets); from an unused root probably meaning to be firm; the earth (at large, or partitively a land): KJV-- X common, country, earth, field, ground, land, X nations, way, + wilderness, world.
heaven: Hebrew word #8064 shamayim (shaw-mah'-yim); dual of an unused singular shameh (shaw-meh'); from an unused root meaning to be lofty; the sky (as aloft; the dual perhaps alluding to the visible arch in which the clouds move, as well as to the higher ether where the celestial bodies revolve): KJV-- air, X astrologer, heaven (-s).
To illustrate the sometimes confusing English translations in our Bible (and showing why a Strong’s concordance is a most valuable study aid), I supple Cain’s discussion with God after God told Cain his punishment. Observe the use of the English phrase “thou hast driven me out this day from the face of the earth”. Here the word(s) “the earth” means ‘soil’ (Strong’s # 127). Surely Cain did not mean “off the face of the whole planet”. For Cain was driven of that soil that he was on into the land of Nod. Cain’s driving away was not global any more that the flood of Noah was global:
13 And Cain said unto the LORD, My punishment is greater than I can bear.
14 Behold, thou hast driven me out this day from the face of the earth; and from thy face shall I be hid; and I shall be a fugitive and a vagabond in the earth [earth here = erets, as in the flood Scripture above]; and it shall come to pass, that every one that findeth me shall slay me. (KJV)
That the reason for the Flood was men's hearts were continually evil and to kill the Giants in Gen 6:1-8, whom were the abominable to God offspring of Adam's daughters and the fallen angels.
That the Flood was restricted to the area were Adam's tribe lived and where this mixing of human and angelic being was taking place (Gen 6:1-7).
That the Hebrew will allow for "earth" being rendered "land, region, country" (and is in other places in the Bible), and that also "heaven" can be rendered "the visible arch in the sky" for as far as the eye can see due to earth's curvature.
That the other races (Black, White, Asia, Hispanic, ...) were untouched by the flood as they lived in another part of the earth.
That the only animals taken onto the Ark were the animals that were found in the region of the Flood (seven of every clean animal, and two of every unclean animal).
You see, God destroyed ALL people in the DAY of Noah, in the DAY of Lot and the DAY of Son of Man (during the destruction of Jerusalem in AD 70) which means locally only, not worldwide.
