According to Quran, God is the creator, it is one of His attributes -- simple as that. Compassion and Mercy comes next on how he deals with His creation. Purpose for us is to worship with our own freewill, that why he put us above angels. Angels doesn't have freewill, but we have. Even we do less than angels but God puts us above angels because when do worship God, we do it by our own freewill. Dr Lang goes into detail about this

*****
The opening scene is heaven as God informs the angels that He is about
to place man on earth. Adam, the first man, has not yet appeared. From the
verses that follow, it is clear that at this point in the story Adam is free of
any wrongdoing. Nevertheless, God plans to place him (and his descen*
dants [6:165; 27:62; 35:39]) on earth in the role of vicegerent or vicar (khal*
ifah). There is no insinuation here that earthly life is to serve as a punish*
ment. The word khalifah means "a vicar," "a delegate," "a representative,"
"a person authorized to act for others." Therefore, it appears that man is
meant to represent and act on behalf of God in some sense.
The angels' reply is both fascinating and disturbing. In essence it asks,
"Why create and place on earth one who has it within his nature to corrupt
and commit terrible crimes? Why create this being, who will be the cause
and recipient of great suffering?" I t is obvious that the angels are referring
here to the very nature of mankind, since Adam, in the Qur'an, turns out
to be one of God's elect and not guilty of any major crime. The question
is made all the more significant when we consider who and from where it
comes.
When we think of angels, we imagine peaceful, pure, and holy creatures
in perfect and joyous submission to God.... This is what gives the
angels' question such force, for it asks: "Why create this patently corrupt and
flawed being when it is within Your power to create us?" Thus they say:
"While we celebrate your praises and glorify your holiness?" Their question
is given further amplification by the fact that it originates in heaven, for what
possible purpose could be served by placing man in an environment where
he could exercise freely his worst criminal inclinations? All of these consid*
erations culminate in the obvious objection: Why not place man with a suit*
able nature in heaven from the start? We are not even a single verse into the
story of man and we have already confronted our (the atheists') main com*
plaint. And, it is put in the mouths of the angels!
The verse ends not with an explanation, but a reminder of God's
superior knowledge, and hence, the implication that man's earthly life is
part of a grand design. Many western scholars have remarked that the
statement, "I know what you do not know," merely dismisses the angel's
question. However, as the sequence of passages will show, this is not the
case at all.
We move now to verse thirty-one, where we fmd that the Qur ' an con*
tinues to explore the angels' question.
And He taught Adam the names of all things; then He
placed them before the angels, and said, "Tell me their
names if you are right." (2:31)
Clearly, the angels' question is being addressed in this verse. Adam's
capacities for learning and acquiring knowledge, his ability to be taught, are
the focus of this initial response. The next verse demonstrates the angels'
inferiority in this respect. Special emphasis is placed on man's ability to
name, to represent by verbal symbols, "all things" that enter his conscious
mind: all his thoughts, fears, and hopes, in short, all that he c an perceive or
conceive. This allows man to communicate his experience and knowledge
on a relatively high level, as compared to the other creatures about him, and
gives all human learning a preeminent cumulative quality. In several places
in the Qur'an, this gift to mankind is singled out as one of the greatest boun*
ties bestowed on him by God.
They said: Glory to you: we have no knowledge except
what You taught us, in truth it is you who are the
Knowing, the Wise. (2:32)
In this verse, the angels plead their inability to perform such a task, for,
as they plainly state, it would demand a knowledge and wisdom beyond
their capacity. They maintain that its performance would, of course, be easy
for God, since His knowledge and wisdom is supreme, but that the same
could not be expected of them. In the next passage, we discover that Adam
possesses the level of intelligence necessary to accomplish the task and
hence, though his knowledge and wisdom are less than God's, it is yet
greater than the angels.
He said: "0 Adam! Tell them their names." When he had
told them their names, God said: "Did I not tell you that I
know what is unseen in the heavens and the earth and I
know what you reveal and conceal?" (2:33)
Here we have an emphatic statement that man's greater intellect figures
into an answer to the angels' question. We are informed that God takes all
into account, in particular, all aspects of the human personality: man's
potential for evil, which the angels' question "reveals," and his comple*
mentary and related capacity for moral and intellectual growth, which their
question "conceals." To drive home this point, the next verse has the angels
demonstrate their inferiority to Adam and shows that man's more complex
personality makes him a potentially superior being.
And behold, We said to the angels, "Bow down to Adam"
and they bowed down. Not so Iblis: he refused and was
proud: he was of the rejecters. (2:34)
We also fmd in this verse the birth of sin and temptation. The Qur'an
later informs us that Iblis (Satan) is of the j inn (18:50), a being created of a
smokeless fire (55:15) and who is insulted at the suggestion that he should
humble himself before a creature made of "putrid clay" (7:12; 17:61; 38:76).
Satan is portrayed as possessing a fiery, consuming, and destructive nature.
He allows his passions to explode out of control and initiates a pernicious
rampage. We are often told that money is at the root of all evil, but here the
lesson appears to be that pride and self-centeredness is at its core. Indeed,
many terrible wrongs are committed for no apparent material motive.
And we said: "0 Adam! Dwell you and your spouse in the
garden and eat freely there of what you wish, but come not
near this tree for you will be among the wrongdoers."
(2:35)
Thus the famous and fateful command. Yet, the tone of it seems curi*
ously restrained. There is no suggestion that the tree is in any way special;
it almost seems as if it were picked at random. Satan will later tempt Adam
with the promise of eternal life and "a kingdom that never decays"
(20:121), but this turns out to be a complete fabrication on his part. There
is not the slightest hint that God is somehow threatened at the prospect of
Adam and his spouse violating the command; instead, He voices concern
for them, because then "they will be among the wrongdoers."
This is probably an appropriate place to reflect on what we have
learned so far. We saw how God originally intended for man to have an
earthly life. We then observed a period of preparation during which man is
"taught" to use his intellectual gifts. Now, Adam and his spouse are pre*
sented a choice, of apparently no great consequence, except for the fact that
it is made to be a moral choice. I t thus seems that man has gradually
become -- or is about to become -- a moral being.
