Physics and Archaeology

Now Physics Today magazine has an article describing how new methods are yielding more accurate dates for our prehistoric ancestors, profoundly affecting our understanding of the past. Neat stuff."

And I can say the world/universe was created the day I was conceived or born.

More importantly, if you want to argue that the world was created with a perfect history, then it is exactly the same thing as if the world developed over time. If the point of what you said is to defend creationism, then don?t limit yourself to just thinking on such a limited scale of fruits and babies. Consider the fact that if you could know the state of every atom, with its rotation, and basically every piece of energy/non-energy then you can predict the future. Given that, if we assume our big bang theory is correct, if some omnipotent force was able create things as it wanted without limitations, then it could have set the ball in motion for the universe and ultimately us (that includes what we are thinking right now), to be exactly like it wanted from the point of initial expansion. In an isolated system, it would be impossible for the future to deviate, what so ever. This includes setting the constants of the universe so that it allows us the ability to investigate the world around us without limits. And since this omnipotent force was able to foresee the future from the point of initial expansion of the universe, then it falls in quite nicely with the thought that this force still interacts with us today, while it may be just an outcome of the initial conditions.

IMHO, this is the best way for a religion to still claim that their god created the world and universe. While we may figure out that the earth is not the center of the universe like originally defended, I seriously doubt science will be able to disprove an event that occurred before the universe was created. But to explain the fact that our thoughts are just a product of the initial conditions of the universe, would annoy people to say the least, if they really understood it of course.

You seem to hold the idea that something could create the earth (and I assume the universe) in detail, in an instant, yet has a linier existence. Why create something to look 25,000 years old when you can just let unfold in front of you exactly as you want it in the same instant.

You know, I hear vague references to the "critical assumptions that have been proven wrong" over and over again, and I've never heard them adequately explained. Most of the "critical assumptions" the young earthers point to are things like "the speed of light is a constant from any frame of reference". I followed your link to the review of that book and read this quote out of it:

No one has ever bred a new species artificially--and both plant and animal breeders have been trying for hundreds of years, as have scientists.

I've heard this one before too. And it's wrong. Way wrong. There are several observed instances of speciation (especially in the world of botany). A good easy read to start with can be found at the Talk.origins Speciation Faq if you're interested in the background and some references to real papers on the issue. I'm sorry, but any book published after 1915 or so that claims that scientists and plant breeders have never been able to come up with new species is blatantly ignoring established facts and probably not worth your time.
