The vast complexity of living things proves that God exists (proof 1)

[SavedByGraceThruFaith]

So there is no need for the experiment you proved my point,

I found a book, never heard of the title, but I know it is a product of intelligence.

There are many products I have come across and had never seen before but I knew they were the products of intelligence.

You knew they were the products of people. Because we know people make things and what the things people make tend to look like. We know things that aren't made by people by the characteristics that distinguish them from things people make: signs of manufacture, similarity to other artificial products, and so on.

Your argument boils down to 'because we can tell that things that look artificial were made by intelligent beings, we can conclude that things that don't look artificial were made by intelligent beings'. In other words, we can tell they're the same because of the way in which they're different.

But we really, really, can't claim that legitimately.

I can give you many products which I have never heard of, or seen. You would conclude that man made it.

It is simple observational science.
