The spread of civilization history?

Question

My questions;

1. the term "caucasian" comes from the regions of Cocasus. It is a modern days' Russia, Ukraine, etc. Does it mean that the people from Africa traveled to Mid-east, then Cocasus and settled on Western Europe?

2. if then, what does it mean by "Indo-Europe" language? what does India have to do with the Europeans?

3. how did human kinds traveled and spread the civilization? I know the first human appeared on earth is from Africa. Did they travel (spread) to many regions in the world? Where did they arrive first? Did they arrive first in India and then went north west toward to Cacasus?

I want to know, how the human ancestors traveled.

4. so called the "asians", especially the chinese, koreans and japanese have Mongolian heritage. Then the Mongolians are actually the "caucasians" traveled to Asia and settled later?

thank you.

Answer 1

Wow. You are covering too much for one question. The time required would fill books.

First, you are confusing the spread of humanity (according to the currently popular "Out of Africa" theory) with the rise of "civilization" which has to do with the formation of cities. The two are NOT the same.

The first site below should give you a better idea about the spread of humanity.

The Proto-Indo-European language is a construct to help explain why Sanskrit shares so many root sounds for words used in living languages. It is based upon the work of Sir William Jones. See the second and third sites below.

In terms of method of travel, the best realistic answer is by water using craft. Sea shores and rivers were the major means.

As for the Mongolians, check out the last site.

Answer 2

O.K. This is a convoluted question. You are on the right track. Must strip away any "loaded" meanings behind terms.
Human kind originated in Africa
Migration from Africa occurred seveal millenia ago.
Mesopatamia and Eygpt and Yangtze Valley Civilizations occurred roughly at the same time.
The term "Caucasian" is arbitrary and is a nineteenth century construct to bolster imperialism.
Indo-European Languages is the overarching catch-all for most modern languages other than Chinese, Amer-Indian, and Aboriginal/Polynesia.
Sounds kinda weak, but true.
Genetically, every one is related.
Don't fall into the trap of Panspermia.
