We know the Earth could not be created in one day. Or that the whole universe did not spring into being in one week.
The Bible is rife with scientific inaccuracies. Like the Flood - all life on Earth, save a boatload of animals and eight people, did not perish in 40 days and nights.
God separated the Light from the Dark as the first Creation. He created the plants on the third day. But the Sun, which the plants needed to survive, didn't exist until the fourth day. Photosynthesis, thus, becomes a thorny issue.
The Biblical account of Jesus' birth tacitly endorses Astrology, which we know to be bunk. The Magi "follow a star" which led them to Jerusalem, and through investigation, to the manger.
The Tower of Babel, which the ancients were going to build all the way to heaven, would surely have collapsed under its own weight during construction far before any omnipotent god had any need to fear it. And that doesn't touch the problem of oxygen/space exposure, or even the location of Heaven. It's a tale told with the mind of a Bronze Age man, not remotely scientifically plausible. Yet, were the story to be believed, it was such a threat to God in Heaven that he had to confound the language of Man to stop him.
Regarding the Pyramids and Egyptians, there's no mystery to whether they could do it or not, we're just trying to figure out how they did. The knowledge isn't godly, it's just lost, in much the same way as I used to be able to do two- or three-digit multiplication in my head until I got my hands on Excel. Since I started relying on spreadsheets, I've lost the knack. The knowledge isn't inaccessible, I'm just out of practice.
