Whatever you think of religion, the glimpses it gives us of the past through its writings are telling.
“Have them make an ark[b] of acacia wood—two and a half cubits long, a cubit and a half wide, and a cubit and a half high.[c] Overlay it with pure gold, both inside and out, and make a gold molding around it. Cast four gold rings for it and fasten them to its four feet, with two rings on one side and two rings on the other. Then make poles of acacia wood and overlay them with gold. Insert the poles into the rings on the sides of the ark to carry it. The poles are to remain in the rings of this ark; they are not to be removed. Then put in the ark the tablets of the covenant law, which I will give you.
This was written 1,500 years before Jesus Christ arrived on the scene. It shows a high level of craftsmanship and skill that was well developed.
The first Biblical references we have, historically speaking, are from the bible’s book of Genesis. It appears that detailed instruction was not unusual.
Here’s another example from Genesis:
Now the earth was corrupt in God’s sight and was full of violence. God saw how corrupt the earth had become, for all the people on earth had corrupted their ways. So God said to Noah, “I am going to put an end to all people, for the earth is filled with violence because of them. I am surely going to destroy both them and the earth. So make yourself an ark of cypress[c] wood; make rooms in it and coat it with pitch inside and out. This is how you are to build it: The ark is to be three hundred cubits long, fifty cubits wide and thirty cubits high.[d] Make a roof for it, leaving below the roof an opening one cubit[e] high all around.[f] Put a door in the side of the ark and make lower, middle and upper decks. I am going to bring floodwaters on the earth to destroy all life under the heavens, every creature that has the breath of life in it. Everything on earth will perish. But I will establish my covenant with you, and you will enter the ark—you and your sons and your wife and your sons’ wives with you. You are to bring into the ark two of all living creatures, male and female, to keep them alive with you. Two of every kind of bird, of every kind of animal and of every kind of creature that moves along the ground will come to you to be kept alive. You are to take every kind of food that is to be eaten and store it away as food for you and for them.”
Noah did everything just as God commanded him.
If there was no tradition of instructing craftsmen, it’s unlikely a person would write down the account with that part made up.
That’s not to say we have to take the bible as um, gospel…
If you want to question the accuracy of the bible there is lots of room to do that, says Farrell Till in his piece at The Skeptical Review.
Another case in point is the biblical record of the exodus of the Israelites from Egypt and their subsequent 40-year wandering in the Sinai wilderness. According to census figures in the book of Numbers, the Israelite population would have been between 2.5 to 3 million people, all of whom died in the wilderness for their disobedience, yet extensive archaeological work by Israeli archaeologist Eliezer Oren over a period of 10 years “failed to provide a single shred of evidence that the biblical account of the Exodus from Egypt ever happened” (Barry Brown, “Israeli Archaeologist Reports No Evidence to Back Exodus Story,” News Toronto Bureau, Feb. 27, 1988). Oren reported that although he found papyrus notes that reported the sighting of two runaway slaves, no records were found that mentioned a horde of millions: “They were spotted and the biblical account of 2.5 million people with 600,000 of military age weren’t?” Oren asked in a speech at the Royal Ontario Museum. That is certainly a legitimate question. Up to 3 million Israelites camped in a wilderness for 40 years, but no traces of their camps, burials, and millions of animal sacrifices could be found in ten years of excavations. This may be an argument from silence, but it is a silence that screams.
