Bismillah. InshaAllah in this post the possibility of human divinity will be discussed (in other words the possibility from a logical perspective if man can be god). At the outset, I am assuming that the reader does agree that something greater exists - atheists can refer to other posts dealing with the denial of God. InshaAllah this post will remind us why the belief in One God is the Truth.
1. God must be Greatest. Logically the Creator is both more complex and knowledgable than the created. Whether it be the world, a man or the Universe the Creator must logically be greater than the created. For example, a carpenter creates a bookshelf but a bookshelf can not create a carpenter (the simple object can not create a complex object, only the opposite is true).
2. Man is imperfect. God is Perfect; whereas man is imperfect and has many flaws. For example, all living beings require sustenance (in other words they can not survive as their own independant being without a provision). Also, created beings have imperfections such as: urination, tiredness, defecation, injury and death. Whereas the Creator of everything is not limited by time and provides sustenance for all existence. Logically the Creator must exist longer than any creation due to the Provision He provides.
3. All humans are created. Of the major religions present around the world, there are some which diefy man as god. Within such theological perspectives none considers such a man to have not been created. For example, within the Christian idoeology, Jesus (upon whom be peace) was born of the Virgin Mary. Likewise within Sikhism, Buddhism, and other religions each respective divine being was created. Thus, if the "god" was created that created being has (or had) a limited existence within time. However, the Lord of the Worlds logically has to exist for all time (eternally).
4. Prayer and Worship. The prayer of such people who are claimed to be gods (and other forms of worship) must be directed toward a greater and external being. Logically a person does not pray for a person/thing which has no ability to answer such a prayer. Thus, the worship and prayer of such men who are claimed to be gods in fact prove that a greater being exists than they (to whom they pray).
May Allah guide us to the Straight Path.
May Allah bless us with stability on that Path.
