This question is Biological in nature, but can be simplified to fit the historical context. Basically, if you isolate two populations, they will adapt to their different environments. The environment in Europe differed than that of the Americas; therefore, Europeans adapted in a different manner than American Indians. One of the adaptions stems from the proliferation of various diseases in crowded cities and close proximity to animals (part of the reason the Black Plague was so disastrous). Because of the number of novel diseases in Europe, Europeans had built certain immunities. The immune systems of American Indians, however, were not familiar with the diseases found in Europe. When introduced to the common cold or influenza, the American Indians could not fight them off. Many millions of native peoples in the Americas died as a result.
The Europeans started to use the Native Americans as slaves.
Christopher Columbus killed many many Native Americans. Europeans also killed many by bringing diseases to america. They (the British and europeans) were sick people, and very greedy, which is why there are very little Native Americans left.
Diseases that were brought to the Americas from Europe. Americans had no immunities from those diseases. What would make a European mildly sick would kill people that had no resistance at all.
Many of the Native Americans died of disease from being around the Europeans. Colonists also traded with Africa and African Americans became more efficient.
Small pox. The natives had no resistence to diseases the europeans carried to the new world.
To get a general idea, the Native Americans taught the Europeans how to farm, kill certain animals, make jewelry (such as bead necklaces), and many other things. In return, the Europeans taught the Native Americans how to use advanced technologic weapons (guns), and taught them the idea of religion.
Many native Americans succumbed to the diseases brought over by the Europeans, as they had no immunity.
The Europeans started to use the Native Americans as slaves.
Native Americans definitely suffered from the westward migration of Europeans.
European diseases killed so many Native Americans because the natives had no natural immunity. It is surmised that hundreds of thousands died.

Many thousands of Native Americans were killed by diseases such as smallpox that was spread to them, intentionally and unintentionally, by white settlers.
Many native American tribes were ousted from their homelands or persecuted to extinction or near-extinction by the colonists. Europeans also brought diseases that were formerly confined to the Old World. Native Americans had not developed the resistance to these diseases and many died.

The spiritual world of the Iroquois included many beliefs and deities. The Great Spirit was one of the most important. Native Americans had no concept or word for 'religion' until the Europeans got involved. What the white men saw as religion is a natural way of life for the Native American. Only the Europeans felt the need to convert. Native Americans did not fight or kill over spiritual beliefs.
