Allah exists in his creations of everything. He is the one who created the tiny atom in all its complicated structure and physics. He is the one who created the largest galaxies and stars and made them in perfection. He is the one who made the Earth very suitable for life of all kinds and in all aspects from air to atmosphere to millions and millions of factors. Allah is the one who gave you complicated brain in which you see, smell, hear, talk, communicate, feel, and the other complicated body systems with perfection. Have you seen a complicated and flexible tool like your hands and how they function with the rest of the body? It is Allah who gave you all of that.
Oh God (Allah) bear witness that I conveyed!
