We have learned about the 'Skeletal Planet' Neptune. Its positioning implies a separation— a river being divided from the land (or 'village' area) by a stretch of sand.
If human settlements on a 'twin Earth' are situated on flat plains—removed from mountains, forests, coastlines, riverbanks, icy regions, or deserts—and, crucially, do not come into contact with mineral deposits, then they are considered to be located on 'Earth.'
If all entities exist as "twin Earths"—where each individual functions as their own sun and pole star—then, given that our bodies are 60% water, we can potentially inhabit a "twin moon" reality.
Fourth-grade students are taught the definition of "mineral resources." They learn that any naturally occurring, usable substances or materials found beneath the soil—or within the Earths crust—are classified as mineral resources.
Creation has a beginning, and it will also have an end. The Great Creator has spoken of a Day of Judgment. This end can be deferred for an indefinite period—perhaps for billions of years.To implement that, one must understand scientific theory of THE BLACK HOLE.
