What on earth makes you think that?"Laws" are the names for the regularities we observe in nature.These regularities exist because there are only a finite number of different basic types of things of which the universe is composed. We can speak, for example of laws of electricity 'cos electrons are all exactly the same as one another.There, that wan't too difficult, now, was it?

Take this as an example: people get drunk if they drink enough ethanol. That's a law of nature, i.e. an observable regularity in nature.Now this law is not a thing having causative power; it's a description of what happens which is always true. The reason it's always true is that all humans have similar biochemistry, and every ethanol molecule has the same chemical properties.

The tendency even has a name: "reification", although unfortunately the word means lots of other things as well. I think you're confusing phogiston with caloric.

A quick 'n' dirty calculation from the inverse square law shows that you could change the radius of the Earth's orbit by about 2% either way and that would change the mean global temperature by about 10C either way.We may note that life is capable of existing even in boiling water, so the habitable zone is much broader than this.Add to this the large number of solar systems in the Universe, and the odds that no planet would fall in the habitable zone of its sun are ... astronomical.Where on earth did you get your figure from?
