The forest hides and destroys stuff extremely well.
Having the Iliad amounts to a cheat code in archaeology.

"How did Americans justify westward expansion?"
"Americans justified westward expansion through the ideology of Manifest Destiny. Manifest Destiny was a term coined in the mid-1840s. It claimed that the United States was providentially designed to spread across the continent. Believing their "civilization" to be superior to Native and Mexican peoples, it supposed their lands should rightfully be part of the United States. This led to the brutal subjugation of Native tribes as millions of Americans flooded west in the decades after the Civil War."
This framing is passive and hides the history that our own government even admits to[1]. The west wasn't simply lightly populated. There were state-sponsored and well documented extermination campaigns that cleared the land for white settlement.

What makes you say that? Some studying the California natives put their population at 300,000, some all the way up to 1.5MM and that's after they were hit by waves of infectious disease.

Both caricatures ofc. But then again, they have to be because in the political arena details and facts don't matter at the end of the day as it's all about marketing.
I don't want to sound mean, but without any links to anything, any mentions of books, papers, even mentions of archaeological finds in local newspapers... what you're saying is just a story about someone you met who made some outlandish claims.
The fact that the argument appears to be cut and dry is also testament to the fact that it has been rehearsed many times and shared within that identity community
The kind of horse that could be domesticated and ridden was not widespread, and in fact were really just hunted for meat until maybe 6500 years ago, and actually riding them came even later...
So, I mean, maybe there were equine species in North America, but their relationship to humans I doubt would be anything like what we think of horses like right now. More like a hunted species like bison or deer...
Now, dromedaries I can see. Camels, alpacas, and llamas etc. Long and ancient history with those, and in both hemispheres independently.
Edit: more like millions of years
They died off (along with mammoths and lots of other large mammals) around the same time as humans arrived in the Americas and hunted them to extinction.
