Dinosaur Extinction and Evolution...?

well you have to understand that dinosaurs are cold blooded meaning they relied on their surrounding to regulate their body temp

That's not strictly true, current theory is that dinosaurs were warm blooded (endothermic). The misconception that they were warm blooded comes from them being labelled as lizards.

I don't really prescribe to Darwin's theory of evolution.
But parts of living creatures are constructed of intricate components with connections that all need to be in place for the thing to work, controlled by many genes that have to act in the proper sequence. Natural selection would not choose parts that did not have all their components existing, in place, connected, and regulated because the parts would not work. Thus all the right mutations (and none of the destructive ones) must happen at the same time by pure chance. That is physically impossible.

Yes, it's impossible. And if that were the actual theory, you might have a point. But it's not, and you don't.

Look into the evolution of the eye sometime. Starts out just a generally photosensitive bit, and gradually develops improvements until you've got an eyeball.

Helps to actually know the subject, not just the religious nut claims. It's like trying to talk about a trumpet but knowing only about kazoos. Doesn't work.

What you're arguing here is irreducible complexity which has been debunked repeatedly. The three examples that are most commonly mentioned as a result of being the three key examples in Behe's book on the subject (the eye, the bacterial flagellum, the blood clotting cascade) have all been shown to be quite reducible.

I have commented on this topic already on another thread.

www.abovetopsecret.com...

Similar forms to the dinosaurs did evolve but from mammals that survived the mass extinction. Creatures as large as the dinosaurs just could not survive in a world where there was a lot less light due to a dusty atmosphere.

Look at the similarity between say some smaller dinosaurs and say the chicken too. Cows have filled the niche left by other dinosaurs. Maybe, as I discussed in the above thread, primates replaced some of the intelligent, bipedal dinosaurs who had opposable thumbs...

There is an ongoing discussion about that very topic here.
