Lots of ancient humans and animals don't have skulls. Doesn't mean they can't be compared to the fossils of other more complete skeletons and tentatively ID'd. Just means they wouldn't be ideal to display in a fossil museum. If you don't believe in a human race, what do you believe in?
I believe they existed. Pretty hard to dismiss the scientific findings back in the 1800’s of what’s thought to be large land reptiles. Scientists can even see evolutionary traces of dinosaurs, in birds of today. Why would scientists make this up?
The U.S. Supreme ruled against the Smithsonian over the denial of the existence of giants. They destroyed thousands of giant skeletons in the 1900s.
To spread their dogma of evolution. Thousands of years digging up the earth and they only find them since the 1840s.
