Hi Many, Assalamualaikum.
I am sure by "creator" you meant ‘Allah’. Allah is the highest 'focus-word' in the Quranic system, which is surpassed by no other word in rank and importance. The Quranic usage of the word provoked stormy discussions over the nature of this CREATOR - God/Allah between the Muslims and the Kafirs, as is most eloquently attested by the Quran itself.
If it be a question of complete and comprehensive knowledge of Allah, then, of course, we must accept that man's ability to know does not extent that far. God's characteristics cannot be placed within given limits, and whatever comparison or simile we offer for them is bound to be false, for whatever is observable to science and thought in the natural realm is the work of Allah and the product of His will and command, whereas His essence is not part of nature and does not belong to the category of created beings.
Hence, the essence of the divine being cannot be grasped by man by way of comparison and analogy.
He is, in short, a being for the knowledge of Whose essence no measure or criterion exists and for the fixing of Whose Power, Authority and Knowledge, we have no figures or statistics.
Is man, then, too abject and powerless to perceive anything of the essence and attributes of so elevated a reality? To concede the weakness of our powers and our inability to attain complete, profound and comprehensive knowledge of Allah does not imply that we are deprived of any form of knowledge, however relative.
The orderly pattern of the universe loudly proclaims His attributes to us, and we can deduce the power and unlimited creativity of the Creator from the beauty and value of nature. Phenomena are for us an indication of His unique essence.
Contemplation of the will, consciousness, knowledge and harmony inherent in the order of being and all the various phenomena of life, makes it possible for us to perceive that all these qualities together with all the other elements that speak of aim, direction and purpose unnecessarily derive from the will of a Creator Who Himself possesses these attributes before they are reflected in the mirror of His chosen / loved creation.
EDIT
The Quran describes the Creator in unique ways:
112:1 Say: He is God, the One and Only;
112:2 God, the Eternal, Absolute;
112:3 He begetteth not, nor is He begotten;
112:4 And there is none like unto Him.
2:255 God - there is no deity save Him, the Ever-Living, the Self-Subsistent Fount of All Being. Neither slumber overtakes Him, nor sleep. His is all that is in the heavens and all that is on earth. Who is there that could intercede with Him, unless it be by His leave? He knows all that lies open before men and all that is hidden from them, whereas they cannot attain to aught of His knowledge save that which He wills [them to attain]. His eternal power overspreads the heavens and the earth, and their upholding wearies Him not. And he alone is truly exalted, tremendous.
Love and Peace for Mankind
