Oxygen. Earth's early(first) atmosphere is believed to contain hydrogen cyanide, carbon dioxide, carbon monoxide, nitrogen, hydrogen sulfide, and water. but still it only had little to no oxygen.
The first layer of the Earth's atmosphere is called the troposphere, and it is in direct contact with the Earth's surface. This layer is where weather events occur and where most of the Earth's clouds and precipitation are found. Temperature usually decreases with altitude in the troposphere.
It's called lithosphere as I remember in science.
The earths first atmosphere was created by the methane, carbon dioxide, sulphur oxides and water vapor that volcanoes were pumping out. Oxygen started to come in noticeable quantities once life had formed. Nitrogen is inert, so doesn't do anything.
the earth first atmosphere is troposphere
The Earth's atmosphere is about 480 kilometers thick, with the majority of its mass concentrated within the first 11 kilometers (troposphere). The outermost layer, the exosphere, extends beyond 10,000 kilometers.

This gas was carbon dioxide.

Earth's first atmosphere contained hydrogen and helium but this was soon stripped away. Another atmosphere began to form and contained hydrogen, water vapour, methane, ammonia, nitrogen and carbon dioxide among other gases.
Actually, the Troposphere Layer can be considered as Earth's first protective layer, because its well-the atmosphere's first layer. You can think of it that way to remember which is Earths first layer.

first of all it helps by : 1. the atmosphere gives earths animals or creations air to breath 2. the atmosphere helps plants grow 3.
On 11 July 1979, Skylab reentered the earths atmosphere.
The first man-made object to leave Earth's atmosphere was the V-2 rocket launched by Germany on October 3, 1942.
