Interestingly, current scientific evidence suggests that this was not at all the "natural state" of North America, and that it was actually a temporary ecological imbalance lasting for a couple centuries after smallpox and other diseases wiped out ~95% of Native Americans after contact from the Europeans -- and suddenly the bison went essentially "unchecked".
Obviously this doesn't change the evil of their almost-extinction or the need for bison as a proper balance -- just that the gigantic hordes of bison that Europeans first witnessed likely isn't the right baseline either.
See "1491: New Revelations of the Americas Before Columbus" for a highly readable account of evidence on both sides from 2006.

For those looking to read it, make sure to get the 400-some page version of this book. There is a similarly named book aimed at grade school kids.

Surprising how innovative and densely populated the people of ancient americas were back then.
If we just take east coast of Maryland, where the author grew up, the first explorers talk about villages that interconnected across the coastline, Chestnut and walnut trees everywhere, and established hunting grounds. Burning was an immensely useful tool to do this. Everyone had a fire starter.
Later on, early settlers saw something drastically different - a dying off population from diseases brought by Europeans that they had no defense towards. And that is why our estimates on the population of the Americas, and the level of which they modified the land could be really off.

>there are billions of stars and planets in our galaxy and billions of galaxies. Humans are rather bad at fully understanding such large numbers.
There's no obstacle to working with large numbers once you understand powers and logarithms (i.e. pre-calc). Very smart people have looked at the Drake equation and it yields a very wide range of values [1].
>Christopher Columbus first landing on North America (not a good event for native Americans)
The main reason Europeans were able to take over America was disease. The Aztec effort to kick out the Spanish was hampered by smallpox [2], and colonization of North America had to wait for over a century before the native population was sufficiently depleted by disease to stop offering resistance. [3] Needless to say, disease worked unintentionally and because both sides were the same species.
> So, screw it, all movie alien races invented artificial gravity.
Or, you know, maybe they built ships with rotating crew habitats that simulate gravity by centrifugal force. (I belive 2001 does a pretty good job of showing the concept.)
> If getting humans to another star system is a 100 on some "technology ability scale", we're a 2 which is not comparatively far ahead of say, poodles - who are probably at a 1.
First off, poodles are at a zero. Second, if 10% of world GDP was dedicated to building an interstellar, multi-generation ark, we pretty much have the technology to do it right now. The technological problem is to reduce the cost to the point where the political will to do it can be summoned (probably around 0.01% of GDP).
>Maybe they want to trade with us. Well, yeah, right. If you've gotten this far it's obvious we have no tech that would interest them.

We already have Google in our pockets. But instantly finding any quote by Darwin doesn't mean I understand the theory of evolution.

The Amazon was, allegedly, basically a garden at one point -- the natives the Spanish eventually encountered were just broken remains of a much larger civilization which had been successful and then disappeared.

It's been a while since I read it but IIRC, the theory is that some of the pigs the Spanish brought with them got loose and went wild, but brought the flu with them. As wild boar spread so did the disease.
