I watched the video (http://www.youtube.com/watch?v=GADt13X3OBI). It said nothing other than what you've already said... look around, stuff is complex, there must be a god because stuff is complex. Someone must have created it all.
How did the flawless order of the whole universe come into being?
Who provided the delicate balances in the world?
How did living beings, incredibility diversified in nature, emerge?
Asking these questions and resigning (submitting) yourself to the easy answer of "god did it" is the way to The Truth?
I am sorry. No. Not going to happen. These questions have very good, god-free, answers.
It isn't flawless in any way.
You kept saying how complex the inner workings of a single cell is. Yes it is. But it is understandable and even though I am not a micro-biologist, I know they have very detailed knowledge of how proteins and DNA and all the other compounds of the inner cell work to do the things they do. The knowledge base of cell mechanics is huge and there is no magic involved. You are going to claim a designer had to have put it all together. No, there are natural paths to how the cells evolved. Chemical reactions are predictable and traceable. It isn't magic. How chemistry works isn't magic, it is even easier than biology to test and examine since now you are dealing with the basic elements and chemical reactions. And these are predictable from the mechanisms of quantum and particle physics. All the way to the big bang we can trace how things work. Our universe is probably only one of infinitely many, each with it's own characteristics. This is the one we exist in. It is that simple. No god necessary.
A month of listening to the Nature podcast would show you how much they know about the inner workings of cells, physics, chemistry, cosmology.
"A Universe From Nothing" by Lawrence Krauss, beautiful talk on the creation of the universe. Clear, easily understood, and it even makes sense!
Short clip to tease you to watch the long version:
Very much worth the time.
Pull yourself out of the grips of this medieval backward belief, it will only drag you down with it.
