People who disregard the existence of Allah and are reluctant to admit that they are responsible to Him seek a logical justification for their stance and a means of convincing other people to agree with them. Claiming that everything has been formed by chance, they try to make people deny the evident existence of Allah and therefore they are not responsible to anyone.
At this juncture, the theory of evolution serves as a so-called scientific mainstay for nonbeliever philosophies. This is why people, who are obdurate in denying Allah, defend this theory as an ideological and philosophical possibility although it has no scientific validity, and no matter whether they believe that it is right or not.
They said, ‘Glory be to You! We have no knowledge except what You have taught us. You are the All-Knowing, the All-Wise.’ (Surat al-Baqara: 32)
