I feel I have to put something in a reply from the many tools we have at our fingertips just to answer you, so with regards the formation of our planet and 7 days, even if you don't believe it or wish to take it as a logical explanation yourself it is one.

It would be a good far as a whole but I do point to a specific paragraph or two.

Taken from a book called reasoning from the scriptures, yes one of our books but very informative in general because all our books and the Bible we use is just the most accurate translations you can get from God's word "The Bible"  that being the first ever writings is scrolls xxx

May i draw your attention to the last 2 paragraphs of the article "creation" 

What is the origin of the raw material of which the universe is made?

Scientists have learned that matter is a concentrated form of energy. This is demonstrated with the explosion of nuclear weapons. Astrophysicist Josip Kleczek states: “Most and possibly all elementary particles may be created by materialization of energy.”—The Universe (Boston, 1976), Vol. 11, p. 17.

From where could such energy come? After asking, “Who has created these things [the stars and planets]?”, the Bible states regarding Jehovah God, “Due to the abundance of dynamic energy, he also being vigorous in power, not one of them is missing.” (Isa. 40:26) So God himself is the Source of all the “dynamic energy” that was needed to create the universe.

Was all physical creation accomplished in just six days sometime within the past 6,000 to 10,000 years?

The facts disagree with such a conclusion: (1) Light from the Andromeda nebula can be seen on a clear night in the northern hemisphere. It takes about 2,000,000 years for that light to reach the earth, indicating that the universe must be at least millions of years old. (2) End products of radioactive decay in rocks in the earth testify that some rock formations have been undisturbed for billions of years.

Genesis 1:3-31 is not discussing the original creation of matter or of the heavenly bodies. It describes the preparation of the already existing earth for human habitation. This included creation of the basic kinds of vegetation, marine life, flying creatures, land animals, and the first human pair. All of this is said to have been done within a period of six “days.” However, the Hebrew word translated “day” has a variety of meanings, including ‘a long time; the time covering an extraordinary event.’ (Old Testament Word Studies, Grand Rapids, Mich.; 1978, W. Wilson, p. 109) The term used allows for the thought that each “day” could have been thousands of years in length.
