A God of Great Details?

In Exodus 25 to 31, it is recorded that the Bible-god went to very great details on some of the things that he wanted Moses to build, right down to the dimensions of each and every part. I find it strange that god would do that, as it is more likely that a human being would do that. We human beings need to go into the last details in our design for everything so that these things will work to serve our purposes. The things to be built does not make much sense to us, viz,

• an Ark
• a Table
• a Lampstand
• a Tabernacle, including curtains, with colors specified; it reads more like a carpenter giving instructions
• an Altar, to be made of bronze, with exact dimensions given; also made to be portable
• a Courtyard
• priestly garments; all parts of the garments mentioned, material specified; now it reads like a tailor giving instructions
• a Breastplate
• An Altar of Incense - so the Bible-god had a nose for smell?

Then the exact procedure for sacrifice is given in great detail in chapter 29. Makes me wonder if the aliens were asking Moses to prepare bbq lamb for them every day????

In chapter 30,
11 Then the LORD said to Moses, 12 "When you take a census of the Israelites to count them, each one must pay the LORD a ransom for his life at the time he is counted. Then no plague will come on them when you number them. 13 Each one who crosses over to those already counted is to give a half shekel, [b] according to the sanctuary shekel, which weighs twenty gerahs. This half shekel is an offering to the LORD. 14 All who cross over, those twenty years old or more, are to give an offering to the LORD. 15 The rich are not to give more than a half shekel and the poor are not to give less when you make the offering to the LORD to atone for your lives. 16 Receive the atonement money from the Israelites and use it for the service of the Tent of Meeting. It will be a memorial for the Israelites before the LORD, making atonement for your lives."

Here, the Lord even asked for a ransom of money for protection!


But why should an almighty God need to do all that? If the Bible-god created everything with his words, why then did he go to such great lengths to get Moses to build so many things, when he could have spoken it into reality?

It reads to me like a group of experts in different fields teaching some backward, undeveloped people in the wild in areas like tailoring carpentry, etc.
