Dinosaur paleontology is a religious racket. Sure there was lots of megafauna and their were some large flightless birds with various levels of feathering. Like anything though money corrupts and the money behind dinosaurs is huge. Every kid has toys, books, theres movies, TV shows, museums, etc.
Sure, dinos for kids are big money, but there's just a massive amount of proof they existed. What proof is there for the world being created in seven days besides a single book of stories invented a couple thousand years ago?

Guessing the orbital mechanics needed to station-keep a signal source at a given apparent sidereal position, far enough from Earth to simulate parallax at infinity, are unworkable.
