Definition of God

A university classmate said he couldn't say if God existed or not, because the very question was ill-posed. He said nobody has actually defined what 'God' is, even though people argue about whether 'God' exists all the time. He said that God was an ill-defined concept, that was is impossible to create a definition of God that was valid, and so there was no way to answer the question.

So to put the question of whether God exists on equal footing, I have created a formal definition:

lim_(power -> infinity) Man == God

It is easy to see that such a limit does not exist. I omit the proof and leave it as an exercise to the reader.

My classmate would say this is not a good definition, but I think it works just fine.
God created man in his image, so man returned the favor.

It's interesting that God is a creator. Creating is a distinctive capability that separates humans from other animals. It is fitting for our egos that God should create the universe as we would have done, rather than birthing the universe or hatching it out of a giant egg like origin myths from other cultures that have a deeper respect for nature.
