We have mountains and continents that took millions of years to get to where we are today. Sorry if my sentences are off, but i just picked up some AK47... mashed. i think it's because I'm cocktailing it with the grapefruit...
The main argument for creation now, it's last stand so to speak, is that the Earth, and us was created around 6, 000 years ago. As this god could not have created the dinosaurs millions of years before man and not made any mention of them before.
to achieve this point the creationists discredit carbon dating, saying it is highly inaccurate, and although it's accuracy is indeed a subject for question, the level to which the creationists question it verges on the ridiculous. Not only do we have carbon dating, we have ice cores and rock cores, these are also discredited by the creationists. They say that we can't possibly judge environmental factors to decide rock and ice formations.
