The first Americans crossed into North America over a land bridge that connected Siberia to Alaska around 30,000 years ago during the last Ice Age. As the climate warmed, sea levels rose and the land bridge disappeared. These early peoples adapted to various environments across North America, developing distinct cultural practices and ways of life. Though diverse, most Native American cultures shared beliefs like respect for nature, communal land ownership, and sustainable use of resources.

1. America In The Beginning Who were the first Americans? This land bridge is known as Beriniga Animals like mammoths crossed the bridge or migrated to the America's. This caused ocean levels to decrease and expose. In the Bering straight a land bridge appeared connecting Siberia/Asia& Americans 30,000 years ago During a period of low temperatures called an Ice Age The world was covered in glaciers or sheets of ice. How and why did they come here?

2. America In The Beginning What happened when they came to America? The ice age ended warmingup glaciers causing water levels to rise covering up the land bridge. Some animals died off like mammoths Living in many different parts of the Americas the Natives needed to adjust or Adapt to every thing in the new surrounds that made up each of their own environment. in order to survive. How did they meet their new needs? Hunter's in Asia who moved from place to place to find food or nomads followed the mammoths and spread out or migrated to the America's

Nature has a Spirit and believe in many gods 2. No one can own Land. 4. Only use what is needed(no waste) 5.Trade was important to most societies Living in many different parts of the Americas the Natives used the different natural Resources in their own different environments for food, clothing, and shelter. What did they have in common?
