The original atmosphere contained only nitrogen, carbon monoxide, carbon dioxide, methane, and water vapor.
Today's atmosphere contains 78% nitrogen, 21% oxygen, 1% shared between argon, carbon dioxide, helium, methane, ammonia, and neon.
Oxygen was lacking in the atmosphere of primitive Earth. Instead, the atmosphere was primarily composed of gases such as carbon dioxide, nitrogen, methane, ammonia, and water vapor.
The primary gases in Earth's primitive atmosphere were likely hydrogen, helium, methane, ammonia, and water vapor. Over time, these gases were likely transformed by geological and biological processes into the current composition of the atmosphere.
Earth's early atmosphere was primarily composed of gases like methane, ammonia, and carbon dioxide due to volcanic activity. Over time, the atmosphere transformed as oceans formed and primitive life evolved, leading to the development of oxygen as a dominant gas. Today's atmosphere is mostly nitrogen and oxygen, which supports complex life forms.
The original atmosphere of Earth was lost when the solar wind of the early sun stripped away all the gas from around Earth. A secondary atmosphere was slowly released by volcanoes as gases were released from the molten rock. Most of this gas is carbon dioxide, but it is gradually dissolved in the oceans and precipitates out as carbonate rock instead of building up in the atmosphere.
Yes, scientists believe that a significant portion of Earth's early ocean water was formed from the condensation of water vapor in the primitive atmosphere, as well as from water-rich materials like comets and asteroids that collided with the planet during its formation.
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.

The four main gases in primitive Earth's atmosphere were nitrogen, carbon dioxide, water vapor, and methane. These gases were likely released from volcanic activity and other processes on the early Earth.
Primitive man used butter as we do today, to eat and to cook with. Sometimes it was used as a dressing for burns or abrasions.
