What are the proofs for the existence of God mentioned by earlier and contemporary scholars, have they reached six, what are the best works on them, and how would atheists respond to them?

The proofs of God's existence are many and manifest in every creature. Contemplating God's cosmic signs and the creation of humans, food, and livestock, such as the heavens and the earth, and the alternation of night and day, leads to faith in His existence and oneness. A servant must not neglect reflecting upon and pondering God's signs, which show that in everything there is a sign from God indicating His oneness. Among the books that have addressed this topic are: "Aqidatullah" (Belief in God) by Dr. Omar Al-Ashqar, and "Physics and the Existence of the Creator" by Dr. Jaafar Sheikh Idris.
