I have heard many creationists say: "Just look at the universe! There are so many things about it that have to be just right for it to be able to support life. This is why I believe in a creator."
An interesting point, so I did a bit of basic math:
The volume of our solar system is: 8.662 x 10^29 Cubic Kilometers
The volume of the earth that is capable of supporting life is: 102,643,270,042.213 Cubic Kilometers
A bit of simple division reveals that only 0.0000000000000000012% of our solar system is capable of supporting life.
This calculation does not even count the rest of the volume of the universe. It seems to me that the universe, contrary to what creationists say, is very hostile to life. It is nearly impossible to find any area where life can survive.
