How can you be their creator?

Juad Ibne Dirham, a leader of atheist sect had kept some mud and water in a glass bottle. After some days worms grew in it and he claimed to be their creator. One day he came to Imam (a.s) and also claimed thus. Imam (a.s) said, “If you are their creator, tell us how many of them are male and how many female?” He said, “I don’t know.” Imam said, “If you can’t do that, command the worms going one way to crawl in the opposite direction.” He said, “I cannot do it.” Imam said, “All right, then tell us what is the weight of each of them?” He replied, “I do not know.” Imam said, “When neither you have any knowledge about them, nor any control over them, then how can you be their creator?”
