I usually like taking part in these discussions, unfortunatly I missed this post (oops)...
I'm definetly Athiest and some other stuff that I really cant be bothered looking up to find out what.
The first thing you have to understand is what the difference between science and religion are:
- Religion is making up stories and then looking for evidence
- Science is collecting evidence and piecing stories together to fit the evidence.
There is a clear difference here, especially in the fact that religions usually shape the evidence to their needs.
A main point that seems to be in everyones arguments is "What created the creator (or big-bang, etc)?". Well, being human, it's fairly complicated for us to understand infinity. The main way I stop myself from getting confused is like this:
Take a piece of graph paper, and plot the graph y = x^2 + 1. Where does it cross the x axis? No where. No matter how far on you go, either tending to positive or negative infinity, the graph will never touch or end up below the x axis.
It's the same for the point before the beginning. Whatever "created" (and I use the term loosely) us existed forever. Now, if you believe in the big bang it's easy enough to say "Well, due to the laws of relativity time probably didn't actually exist until after the start of the big bang" which confuses the issue even further, but meh. It actually makes sense to me, in a way.
And as for evolution, evolution is waaay more logical than "omfg we appeared because someone made us!".
My prime example is the evolution of small bacteria into plant and animal life. Most people say, "well how the hell could I have evolved from a plant?". The answer is fairly simple.
In the beginning you have two types of cell: Plant Cells and Bacterial Cells. Plant Cells as most people know, take in CO2 and produce Oxygen. Bacterial Cells (at the time) simply used Glucose and ATP <-> ADP + Pi as a form of energy (glycolysis). This produced minor amounts of CO2 (for the plants). Suddenly, once there was enough Oxygen available, we begin to see the evolution of aerobic respiration, which produces 19 times more energy than glycolysis alone, (via Krebs Cycle and the Cytochrome System), and the beginning of life as we know it begins.
I see no mention of this in the holy book of any religion, but you'll see it in lots of science textbooks.
PS. The thing about the lower rib is because the lower rib directly protects the diaphragm, which if damaged is pretty damned bad. (You won't be able to breathe) It's also much more sensitive than the other organs, the heart and lungs could survive minor forces on them, the diaphragm wouldn't be so lucky.
