Because we are mammals, and that's the way God made us.

You know the clock analogy don't you ? If the entire existence of earth was scaled to 24h, the existence of mankind would only take up the last 5 minutes or so. Evolution is slow, 5000 years is nothing compared to the timescale of evolution.
I've studied that in my IPC class. Yes, I've heard of it. It's rather interesting, but untrue if you believe in Creationism.

Belief is important. If I believed that killing someone would prevent the earth from ending I'd do it. Suicide bombers believe they are doing the right thing. Belief is a very powerful thing. It just requires... belief. Holding up a view on the origins of species requires one hell of a lot more than that - or at least should do.

I agree. Try arguing with 10 people on a matter for a few hours and see how long you stay clear minded.

Does God make sure they work too ?
Has this been scientifically proven? Do they have examples of them in little slides you can look at under a microscope? If they do, then sure, that's a corrective program, basically, created by God, to where if something's wrong it corrects it. But, that process isn't the same in all the induviduals in a species, so therefore wouldn't work in an evolutionary standpoint.

Normally, under uncivilised conditions, an animal would gain some different traits, eg perhaps being an albino. Now, if you were an albino in the North Pole, and hence were a camouflaged predator or prey, it is an advantage, and the chance of you living long enough to reproduce is increased. Similarly, an albino herbivore prey living in the jungle will get spotted and made into lunch quickly, and die before it can reproduce. Hence, the more wanted traits will get passed down more, and the species changes. I forgot the link and the site, but I've read an article showing that even in the past 100 years or so, the 'tall' gene has become more prevalent within the homo sapiens species.
Two words, Natural Selection. Nice examples Ti!
