The arguement that recently convinced me of god's existence

[Allinlife]

So my close christian friend lends me a book, because I've always been bugging her and questioning christianity, and she told me it'd answer most of my questions.

So I start reading the book and the very first chapter talks about this.

Say you are walking down a field, and you see a wooden chair in middle of no where. Now you know someone must have made that chair, because chair's don't just "happen". You've never witnessed the builder of the chair working on the chair, but you could only assume that someone out there, made the chair and placed it there for whatever reason.

Now if something as simple as a wooden chair can't just "happen" the book argues that something as complicated as humans, cell structures, plants, animals, countless laws of physics that govern the universe could not have just "happened". Somebody must have created us. If you think a wooden chair could not exist with out a builder, consider how infinately more complex body structures we humans have.

And I think the reasoning is fairly solid. I do now think that it is silly to imagine things like mitosis, DNA, human eyes could have appeared by random chance.

The book also goes into absolute lack of evidence in macro-evolution (aka missing links) and how the scientists were still unable to create life out of chemical reactions as they proclaim.

But I do not want to get into the macro evolution/ biogenesis theory stuff, but just would like a discussion on use of logic in the chair anology.

thanks.
