"It was so big it wiped out the dinosaur, but the monkey survived and stood upright to evolve into man."
There were no monkeys, moron.
"Where's this nine mile wide rock now?"
Vaporized. I'd guess you've breathed in, eaten something composed of or in some other way come into contact with its atoms though.
"Dinosaurs are Hollywood folks."
You realize the ancient Greeks and Chinese, among others, were digging up their bones quite regularly, don't you?
"All the photos and models are footnoted: "artist renditions"."
No, they're not. Some are, of course, but certainly not all. The ones that are footnoted as such are called that because we don't know what color they were, what exactly the skin looked like for the vast majority and other subtleties. The overall anatomical structure of the model/illustration is entirely accurate to the best of our knowledge.
"Why don't they put their studying to good use, like making a decent battery, or portable water desalination."
That would be chemistry, physics and engineering. Paleontologists, who are fucking biologists wouldn't be much help.
"Now that they think the dinosaur mystery that never was, is now solved, can we move on to important things?"
No. Now they get to answer all of the new questions that come up from the previous answer. That's how science works. It's a never ending quest for the answers to the new questions that the old answers brought up.
"That waste of time and resources did nothing for us."
You don't think having a better understanding of the history and biodiversity of our planet is helpful in any way at all?
You're quite short sighted.
"Its just another tower of babel."
Speaking of things that never happened...
