What was Earth like 26000 years ago? The last ice age (or Last Glacial Maximum) peaked around 26,000 years ago.

How did humans look 10000 years ago? Humans looked essentially the same as they do today 10,000 years ago, with minor differences in height and build due to differences in diet and lifestyle. But in the next 10 millennia, we may well have refined genetic ‘editing’ techniques to allow our children to all be born beautiful and healthy.
When was fire discovered?
Claims for the earliest definitive evidence of control of fire by a member of Homo range from 1.7 to 2.0 million years ago (Mya). Evidence for the “microscopic traces of wood ash” as controlled use of fire by Homo erectus, beginning roughly 1 million years ago, has wide scholarly support.
When did the first humans appear? Bones of primitive Homo sapiens first appear 300,000 years ago in Africa, with brains as large or larger than ours. They’re followed by anatomically modern Homo sapiens at least 200,000 years ago, and brain shape became essentially modern by at least 100,000 years ago.

When did Indians come to America? Immigration to the United States from India started in the early 19th century when Indian immigrants began settling in communities along the West Coast. Although they originally arrived in small numbers, new opportunities arose in middle of the 20th century, and the population grew larger in following decades.
Where did the Indians come from?
Indian population originated in 3 migration waves from Africa, Iran & Asia. The Indian population originated from three separate waves of migration from Africa, Iran and Central Asia over a period of 50,000 years, scientists have found using genetic evidence from people alive in the subcontinent today.
What was America called before? On September 9, 1776, the Second Continental Congress adopted a new name for what had been called the “United Colonies.” The moniker United States of America has remained since then as a symbol of freedom and independence.
