Some proofs for me are...
I exist. I am fearfully and wonderfully made.
Birds, fish, and flowers have designs that are like from an artist- detailed, skilled, beautiful.
The great crowd of witnesses throughout history, writings, and the domino effect.
I believe good and evil each have a source.
But mostly, I do not think it is logical to conclude that intelligence could come from nonintelligence. That a car has to have a maker, a watch has to have a designer. The odds of putting all the pieces of a watch in a bag, and shaking it, and being able to pull out a working clock are easier for me to believe than life suddenly existing all on it's own.
