Out of this world: Thousands of dinosaur footprints uncovered in China

Whenever I get overwhelmed by daily stress and a billion of tedious tasks I like to read something like this piece of news on yahoo - just gives some perspective.
These dinosaur footprints in China are believed to be more than 100 million years old!! - can you grasp that? It has only been 2010 years since Jesus was born and archaeologists today find animal remains that are millions of years old...
It just makes you wonder: who else was living in that world, with the dinosaurs? What was before that? Who exactly were the first intelligent conscious beings on Earth?
I know I don't have answers, but I also don't have answers to questions such as, why can't we all live in peace and enjoy this world and travel? Who is in control, really??
There are so many 'unknowns' in this life - so, like I mentioned above...such news just give me some perspective...

BEIJING (AFP) – Archaeologists in China have uncovered more than 3,000 dinosaur footprints, state media reported, in an area said to be the world's largest grouping of fossilised bones belonging to the ancient animals.
The footprints, believed to be more than 100 million years old, were discovered after a three-month excavation at a gully in Zhucheng in the eastern province of Shandong, the Xinhua news agency reported.
The prints range from 10 to 80 centimetres (four to 32 inches) in length, and belonged to at least six different kinds of dinosaurs, including tyrannosaurs, the report said Saturday.
Wang Haijun, a senior engineer at the Chinese Academy of Sciences, said the prints faced the same direction, Xinhua said.
This indicated a possible migration or a panic escape by plant-eating dinosaurs after an attack by predators, Wang added.
Archaeologists have found dinosaur fossils at some 30 sites in Zhucheng, known as "dinosaur city."
The region has seen two major digs since 1964, and experts say the discovery of so many dinosaurs in such a dense area could provide clues on how the animals became extinct millions of years ago.
Plans are being made to set up a fossil park in the area.
