What you said is fair enough, but I think the Quran does a pretty good job of "putting Allah on a human level". For example, love is a human emotion. We can even quantify love by examining hormones involved in love. Take Quran 3:31, for example,
"Say, (O Muhammad, to mankind): If ye love Allah, follow me; Allah will love you and forgive you your sins. Allah is Forgiving, Merciful."
Anger is another human emotion/reaction. There are several verses that mention the anger of Allah. For example, Quran 3:162:
Is the man who follows the good pleasure of Allah Like the man who draws on himself the wrath of Allah, and whose abode is in Hell?- A woeful refuge!
Quran 38:27 claims Allah created creation with a purpose in mind:
Not without purpose did We create heaven and earth and all between! that were the thought of Unbelievers! but woe to the Unbelievers because of the Fire (of Hell)!
However, it does not tell us what this purpose is. So we are left wondering: What is the point of existence? Is it necessary? If humans were created only to serve Allah then that would make Allah extremely egotistical. People with big egos demand reverence.
By the way, having children is no problem for the Christian god.
