Explanation:
The European settlers in what is now the United States quickly started to push the natives of their lands and create their colonies. As they were doing so, they started to establish towns and villages, create their own plantations, implement their rules and laws. But this was all happening along the eastern coastline and in close proximity to it. The reason for this was that they had a very big natural barrier in front of them that didn't allowed them to spread out toward the west. This natural barrier were the Appalachian Mountains. The Appalachians are a mountain range that separates almost all of the eastern coastline area from the interior of the country. These mountains are relatively high, had very dense impenetrable forests, and were very dangerous for crossing, so the Europeans avoided them until they developed better means of travel and transportation.

That religion may not be the end all be all of every scientific question ever posed. What I mean is that religion may not be able to answer every question that comes from the world around us, an example being how religions interpreted the Earth as being the center of everything, when scientifically this is not the case and religions disputed this until they eventually died out or re-evaluated their beliefs.
