I have not questioned all the people in the world, so I cannot answer you,
However I do know that truth is truth regardless of what any number of people think.
I also know you have not checked your history very well if you think people here are the only ones who ever thought people and all other animals existed together in time. The Greeks and Romans had very complete carvings and paintings of some of them on their pottery and friezes. Alexander the Great's history has a record of them running into one, which terrified the men. The Egyptian histories record the 'flying lizards.' The Chinese knew 'dragons.' Some carved stones from ancient MesoAmerica definitely look to be dragons/dinosaurs.
People most certainly knew them and often feared them. It's just the 'modern scientists' who cannot afford to have them around at the same time as people. It really messes up their theories!
