Javaro, I have seen enormous amounts of intelligent design in nature! The workings of the cell itself are incredibly intricate and even self-correcting. The pollinization of flowers, the embryo's sustenance and growth, photosynthesis, your circulatory and nervous and digestive systems -- Dawkins himself admits the brain is immeasureably more complicated than a computer (although he claims evolution did it!), and I doubt even you would claim a computer is an accident of electrons and metals! These things and so many more not only exhibit design, but fantastically intelligent design.
Why don't electrons spiral into the nucleus and cause all atoms to disappear in an instantaneous flash of light? Standard quantum physics has no idea why not. But some energy balance in the universe has been created and designed so that what physics says SHOULD happen, doesn't -- and thus we are still here.
Intelligent design? It requires deliberate and constant ignorance and suppression of the truth to deny it in what we see around us.
In the meantime, if c isn't decreasing, what are you going to do with all the data that not only says that c is decreasing, but that associated 'constants' have been measured as changing in conjunction and balance with it? You are not only ignoring, it seems to me, what you see around you, but what brilliant minds in physics and other fields have charted and discussed.
You do seem to be arguing for the sake of arguing without a shred of evidence to back up anything you are saying.
You are proclaiming things you do not seem to know much about and then proclaim that the truth is 'your' truth. Dear fellow (I assume you are a fellow), if, for instance, the speed of light has changed in the history of the universe, that is just as true for you as anyone else. It is either absolutely true or absolutely false. It can't be true one moment or for one person and not true another moment or for another person.
