Things are the way they are because.....

There is an argument put forward by those who believe in divine creation that there has to be an intelligent creator. In essence they argue that if parameters and physical laws which govern the Universe were not precisely as they are, when they could so easily have been different, then we would not exist. Ergo, there must be a intelligent being who created them thus.
If one is already convinced that there is a God then I guess that this argument provides a reassuring riposte to those who point to a scientific explanation.
But is it really so astounding that these paramenters are exactly as they are? Well, yes, but they are, and it is perfectly possible and logical for these conditions to exist without divine intervention. The argument is put forward that the chances of exactly the right conditions for life existing are so incredibly small that it just can't have happened without a guiding hand.
But consider this. If I buy a ticket for the UK national Lottery, the chances of my winning the jackpot are so infinitessimally small, that many people call it a "tax on stupid people", but the fact remains that almost every week one person who buys their ticket in the knowledge that winning is incredibly unlikely, wins that jackpot.
There is a fundamental difference between something being highly improbable and being impossible Our existence may be highly improbable, given the vast range of alternative values that could have existed, but it is not impossible, and it can be deduced and explained using the basic building blocks of the structure of our Universe. There is no need for God.
