You are 100% correct about humans not finding dino bones. However, we may have rocks which formed around those bones. Fossilized dino bones aren't the only thing we have found. We have also found a vast majority of Earth's species in the form of fossils. More than 99% of the species of life which have existed on Earth are now extinct, only to have been found in fossil form.This means that for every species living on this planet today, we have found 100 more fossils of species that no longer exist.
Are you suggesting that for every species of life on mother Earth, our ruling class has fabricated another 100 species? That means every single one of those literally countless fossils have been fabricated by man.
