I don't know much about this subject but it seems odd to me that museums of dinosaurs seem to be all over the place. Yet the bones of the dinosaurs in these museums are all replicas. It's like the government decided to convince everyone on the dinosaur story around the same time. Hollywood too got into the dinosaur game and dinosaurs tend to be added to the curriculum at all schools.
Yet despite all this, I've heard reports that the real bones found might not actually be reconstructed in the way in which they have been. Scientists thought the dinosaurs were reptilian like now they think bird-like. Some people think the ones are just from wild animals that existed not so long ago. Like big Lions or Wolves that went extinct.
Have we been lied to about the existence of dinosaurs in the first place?
I think it's pretty likely that this is the case. I also think the timelines are basically completely made up. They can't even figure out within multiple orders of magnitude shit that was only supposedly 500,000 years ago, but we're supposed to believe they are accurately dating shit from 300-65 million years ago, etc.
BTW, if you haven't already, do nukes next. There's a pretty good argument to be made that nuclear bombs are fake and gay, and that all of the large explosions recorded are much smaller than they're made out to be, and that they were created with large stacks of TNT (like this: https://ahf.nuclearmuseum.org/wp-content/uploads/2015/07/100%20tons%20platform%20and%20crew%20that%20stacked%20it.jpg).
