Is there anyone who isn't at least a little skeptical about evolution?

Personally, I'm skeptical about the Chixculub asteroid being responsible for killing off the dinosaurs. There's still a live debate over whether they held on for hundreds of thousands of years after the asteroid hit, in which case it'd be hard to argue that it really was the asteroid that killed them.

That's the kind of legitimate debate within mainstream science that's occurring WRT evolution. And even then it really has nothing to do with the theory of evolution per se - it's just a controversy about a specific event in history and its aftermath.

But that's a matter of definition. How long does a victim have to survive a gunshot before it becomes 'non-murder'?

The dating of asteroid and the demise of dino is clearly correlated.

The possibilities:

• Pure coincidence -- keep looking.
• Just their time to die -- There is already evidence that a few species had died out or were on the decline. But why the sudden slam 65Mya?
• The asteroid
  1. Heat pulse. -- Dinosaurs died within a few hours due to sudden rise in temperature.
     Species that could burrow in holes or shelter in water mammals, birds, crocodilians, snakes, lizards, turtles and amphibians survived.
  2. Cold climate. -- The dust and ash in the athmospere altered the albedo balance.
     Lush flora died out, starving the herbivores. Large carnivores died without prey assuming their metabolism was up enough to catch it. The survivors would have been those that lived on sparse vegetation, insects or fish.
  3. Poisoning -- Dust and ash in the athmospere (as above) included various compounds that the dinosaur population couldn't handle.
     In addition to outright death, poisoning could include disruption of the development of the embryo, egg calcium or gestation or maybe even behavioral changes; such as not recognizing a potential mate.
     The offending compound(s) might even be something we consider totally innocuous such as salts or sulphates. Survivors would have been those with liver metabolism to deal with it.
  4. Something we haven't considered -- space aliens, mass murder-suicide ...
  5. Combination of the above -- If you assume dinosaurs were well adapted to their environment and biologically 'fit', then you'd have to expect several factors would be needed to wipe out an entire superfamily such as Dinosauria.
     Aves could be considered to have fallen through the 'cracks'.

Until the observations come in that can support any of the above, I think you're right to be skeptical.
Extinction by asteroid should be a strong hypothesis, nothing more. It's not quite up to the term 'theory', IMO.
