A building is proof that there has to of been a Builder. A painting is evidence there was a Painter. A banana is an example natures proof of a designer. eg colour-coded for freshness, pull tab to open it, the outside is 5 sided and snuggly slots into the thumb & first finger, etc.
Creation itself evidences a Creator.

Good old argument from design. I think David Mills sums it up the best:
David Mills said:If creationists want to believe that all lifeforms were carefully and purposefully designed by a Creator, then they must accept the Creator's abysmal 99 percent failure rate. Any watchmaker whose product similarly failed would be dismissed as incompetent.
And if you want to go on about bananas why not read this? (NSFW I guess.)
Yet we divide our calendar into weeks. So where did we get our week from ?
Babylonians.
