a question about dinosaurs

Don’t you think if, as some christians claim, dinosaurs existed around 6000 years ago, as the same time as humans, that they would have been mentioned at some point in the bible? maybe something along the lines of:

Then Moses led his people out of Egypt, and a huge stegosaurus did cometh out of fucking nowhere. And all hell broketh loose.

-oh fuckity shit a dinosaur 4:12
