there was nothing, and then the nothing exploded and created everything"
No current theory says that.
Bob: what science is "discovering today" is knowledge that was lost thousands of years ago but well kniown then.
Perhaps you would be good enough to provide some examples of that.
The Pyamids are exactly aligned with the three stars of the Orion Belt; Black Africans knew exactly what the Pleiades were before any white man told them.
The Great Pyramid is nearly perfectly aligned along the cardinal points—north, south, east and west—with “an accuracy of better than four minutes of arc, or one-fifteenth of one degree.
The glue that holds the Pyramids together is near indestructalbe and no modern science knows how it was made., plus regardless of silly THEORIES, that change as often as the wind, about how the blocks that the Pyramids are made of were moved, they have no idea how they were able to move them to where they are or how they were quarried as drill holes are known to exist and no known society of the time had metal tools capable of drilling into granite, etc, etc, etc.
