The underlying theme in all Christian theology and teaching is the concept that God created everything. Christianity does not teach a theology of random, arbitrary chances that made everything coming into being. This is stated simply in the Apostles creed and expounded in the confessions.
God created everything
While Christians believe God the Father created all things, we equally believe creation was done by the Son (the Word) and the Spirit of God as well. The Westminster Confession of Faith puts it clearly in the following quote.
It pleased God the Father, Son, and Holy Ghost, for the manifestation of the glory of his eternal power, wisdom, and goodness, in the beginning, to create, or make of nothing, the world, and all things therein whether visible or invisible, in the space of six days; and all very good.
Westminster Confession of Faith Chapter 4 Of Creation
The Bible clearly teaches that creation was not just a one time incident; but, a time transcendent act. Though the creation story tells us that God created the world in six days and rested on the seventh, this does not mean God simply set everything into motion and let the world go in its own way unregulated. All of creation was created, past present and future by God in six days.
The heavens are Thine, the earth also is Thine; The world and all it contains, Thou hast founded them. The north and the south, Thou hast created them; Tabor and Hermon shout for joy at Thy name. Thou hast a strong arm; Thy hand is mighty, Thy right hand is exalted.
(Psa 89:11-13 NAS)
Remember what my span of life is; For what vanity Thou hast created all the sons of men!
(Psa 89:47 NAS)
This will be written for the generation to come; That a people yet to be created may praise the LORD.
(Psa 102:18 NAS)
Everyone who is called by My name, And whom I have created for My glory, Whom I have formed, even whom I have made.”
(Isa 43:7 NAS)
“Do we not all have one father? Has not one God created us? Why do we deal treacherously each against his brother so as to profane the covenant of our fathers?
(Mal 2:10 NAS)
For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
(Eph 2:10 NAS)
For everything created by God is good, and nothing is to be rejected, if it is received with gratitude;
(1Ti 4:4 NAS)
While the naturalist will object to this and say God doesn’t interfere with creation; but, just watches over it from heaven, the Bible clearly teaches something different. God does not have any location in which he resides.
The Son of God (the Word) and the Spirit of God Created everything as well
It is perfectly clear the the Son of God, the Christ, created everything.
For He delivered us from the domain of darkness, and transferred us to the kingdom of His beloved Son, in whom we have redemption, the forgiveness of sins. And He is the image of the invisible God, the first-born of all creation. For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities– all things have been created by Him and for Him.
(Col 1:13-16 NAS)
in these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world.
(Heb 1:2 NAS)
You can see a clear statement about the Spirit of God creating man in the following quote from Job.
The Spirit of God has made me, And the breath of the Almighty gives me life.
(Job 33:4 NAS)
The nature of God is not comprehensible to the human mind
God is not comprehensible to a human mind because we are finite. We can only hold so much information. God is infinite. We can no more fully comprehend God than we can count to the last number or fly out to the ending point of outer space.
“God thunders with His voice wondrously, Doing great things which we cannot comprehend. “For to the snow He says, ‘Fall on the earth,’ And to the downpour and the rain, ‘Be strong.’
(Job 37:5-6 NAS)
This is also true for His creative acts. To try and explain how God created everything from nothing is futile. We cannot figure out God’s creative power and fully understand how He works in creation. Explanations like the “Big Bang” and “Evolution” cannot be proven nor are they adequate explanations of God’s creative power. We can apprehend God in what is revealed in His Word; but, to fully understand the works of God is an impossibility to a finite creature.
God did not create evil or nor is He uncaring
This is not to say God is uncaring, evil, or the creator of sin either. God is complex and beyond our ability to understand His ways. He not only will hold all accountable to their deeds; but, also forgives and causes good to come forth on earth.
Then the LORD passed by in front of him and proclaimed, “The LORD, the LORD God, compassionate and gracious, slow to anger, and abounding in lovingkindness and truth; who keeps lovingkindness for thousands, who forgives iniquity, transgression and sin; yet He will by no means leave the guilty unpunished, visiting the iniquity of fathers on the children and on the grandchildren to the third and fourth generations.”
(Exo 34:6-7 NAS)
We can by no means say,
“Why does He still find fault? For who resists His will?”
(Rom 9:19 NAS)
Paul’s answers was,
On the contrary, who are you, O man, who answers back to God? The thing molded will not say to the molder, “Why did you make me like this,” will it? Or does not the potter have a right over the clay, to make from the same lump one vessel for honorable use, and another for common use?
(Rom 9:20-21 NAS)
God created everything the way it is to show His mercy,
And He did so in order that He might make known the riches of His glory upon vessels of mercy, which He prepared beforehand for glory,
(Rom 9:23 NAS)
God is merciful, loving, and kind.
