The question of the so-called "fine-tuning" of the universe and its basic constants is one of the pet arguments of theists. One of the main reasons for it is that there is no obvious explanation

There are essentially four possible explanations:

• This fine-tuning is highly unlikely in a random possible universe, but God has ensured in his loving wisdom that it is so, so that we can come into being.

• This fine-tuning is highly unlikely in a random possible universe, but just by luck the one that exists is anthropic.

• This fine-tuning is highly unlikely in a random possible universe, but there are such a vast number of other
  universes that it is not unlikely that at least one of them is anthropic.

• There are as yet undiscovered reasons why this fine-tuning is not highly unlikely in a random possible universe.
