If Locust are 1 inch and dig 12 feet deep and sleep for 10 years whos to say a dinosaur 1 million times its size didnt dig 12 million feet deep and slept for 10 million years? Explain that.   Can you dig 1 million feet to check? Lets just say its 13 thousand years and we are dinosaur food... if we learned to talk in 200k years whos to say dinosaurs didnt learn it over millions of years.
