What gas was not present in the atmosphere of primitive earth?
Primitive Earth (Before life) contained no or very little Oxygen (element#8)According to scientific theory:Earth had no oxygen to begin with. It had a lot of carbon dioxide, though. Somehow (We still do not know how they started growing) single-celled Carbon Dioxide-breathing bacteria slowly, over thousands to millions of years, turned most carbon dioxide into oxygen, supporting new types of life.:)
The primitive earth's atmosphere did not contain?
free oxygen
How does the troposphere affect life on earth?
The troposphere is where most life on earth lives. It is where we have our air and makes our weather.

Why are scientists who are searching for life on other planets studying Archae bateria?
Archaebacteria are the oldest and most primitive forms of life on planet Earth. It is postulated that primitive life on other planets would be most likely to resemble Archaebacteria. In addition, Archaebacteria were the first life forms to exist on Earth, so studying them allows xenobiologists to postulate how life may come into being on other planets.

Most meteorites are rocky and primitive.
Is RNA a thought to be the oldest and most primitive coding mechanism for life?
Yes it is the oldest and most primitive coding mechanism
Is the sun the source of energy in most energy resources?
The Earth has two sources of energy, the sun's radiation and heat from inside the Earth. The sun is most important and life could hardly exist except at a very primitive level without it.
The first cells to evolve in primitive earth were most likely members of the domain?
Bacteria
Can the box jellyfish see?

What geological period has fossils of the most primitive life forms?
20,000 b.c.
Was Earth colonized by extraterestrial man when there where primitive man on Earth?
No.
Were the conditions of primitive earth suitable for life?
No one really knows. A new theory proposes (with substantial evidence) that there is a higher possibility of microscopic life forming in comets than on early earth. This theory speculates that life reached earth via this transportation system.
