If there is no God, then, one may ask

[The Reality Salesman01]

Would be very interesting to hear the arguments of those who think it's a man who governs the whole order of things on earth and not God.

That all depends on what you mean. Arguments can be made about Man holding the keys to many things on earth, and I'm sure something could be said about our potential to bring earth as we know it to a hault. But as far as the governing laws we use to describe the usual order of things from our human perspective on earth, they are not things that are regularly manipulated. If they were, it wouldn't be very helpful to assume them as norms, would it? Now, God? I'm not sure what that adds to the question.

We can either try to understand more about the earth so that we may have a more positive influence on what we can control, or we can insert God and profess it all to be unknowable and out of our control. The latter suggestion is intellectually bankrupt. The most honest approach to answering this rather silly question would be-

There are things we do not understand, and others we do. Through our knowledge, we as men, can choose to control or ignore the matters within our scope of influence.
