What was Imam Ghazali's proof that god exists?

Imam Ghazali, also known as Al-Ghazali or Algazel, was a Muslim theologian, jurist, philosopher, and mystic who lived in the 11th century. He is considered one of the most influential figures in the history of Islam and has had a significant impact on the development of Islamic thought. Ghazali's proof of the existence of God is based on a combination of philosophical argumentation and spiritual insight. Here are ten points that summarize his main arguments: The argument from causation: Ghazali argued that everything in the universe must have a cause, and that the ultimate cause of everything must be an uncaused cause, which he referred to as the Necessary Being or God. The argument from design: Ghazali observed that the natural world exhibits a high degree of order and complexity, and argued that this could not have arisen by chance. Instead, he believed that it must be the result of an intelligent designer, namely God. The argument from desire: Ghazali argued that human beings have a natural desire for happiness and fulfillment, and that this desire can only be fulfilled by God, who is the source of all goodness and perfection. The argument from morality: Ghazali believed that moral values, such as justice and mercy, are objective and universal, and therefore must be grounded in something outside of human beings. He argued that the only explanation for this is the existence of God, who is the source of all moral values. The argument from prophecy: Ghazali believed that the existence of prophets and revelation was evidence of the existence of God, as it demonstrates that God is concerned with the well-being of humanity and is willing to communicate with us. The argument from miracles: Ghazali believed that the occurrence of miracles, such as healings and other supernatural events, was evidence of the existence of God, as it demonstrates that God is able to intervene in the natural order of things. The argument from spiritual experience: Ghazali argued that the inner spiritual experiences of mystics and sages, such as feelings of unity with God and the divine presence, were evidence of the existence of God. The argument from the nature of the universe: Ghazali believed that the intricate and complex nature of the universe, including the laws of physics and the properties of matter and energy, indicated the existence of a wise and powerful creator, namely God. The argument from the beauty of the natural world: Ghazali argued that the beauty and majesty of the natural world, such as the beauty of flowers and the grandeur of mountains, were evidence of the existence of God, who is the source of all beauty and excellence. The argument from the human need for God: Ghazali believed that human beings have a natural inclination and need for God, and that this need can only be satisfied by the existence of God. It is important to note that these arguments are not intended to be exhaustive or definitive, but rather to provide some of the key ways in which Ghazali approached the question of the existence of God. “There is no denying existence itself. Something must exist and anyone who says nothing exists at all makes a mockery of sense and necessity. The proposition that there is no denying being itself, then, is a necessary premise. Now this Being which has been admitted in principle is either necessary or contingent… What this means is that a being must be self-sufficient or dependent… From here we argue: If the being the existence of which is conceded be necessary, then the existence of a necessary Being is established. If, on the other hand, its existence is contingent, every contingent being depends on a necessary Being; for the meaning of its contingency is that its existence and non-existence are equally possible. Whatever has such a characteristic cannot have its existence selected for without a determining or selecting agent. This too is necessary. So from these necessary premises the existence of a necessary Being is established.” (Source: Fada’ih al-Batiniyya, p. 82)
