The Earth's early atmosphere was likely formed by volcanic activity, which released gases such as water vapor, carbon dioxide, nitrogen, and methane. Over time, this atmosphere evolved as a result of various geological and biological processes.
Earth's present atmosphere is believed to have originated from volcanic activity early in the planet's history. Volcanoes released gases such as water vapor, carbon dioxide, and nitrogen, which eventually formed the atmosphere over billions of years.

The era that began with the formation of Earth's atmosphere is the Hadean Eon, which lasted from about 4.6 to 4.0 billion years ago. This was a time when Earth was still forming and experiencing intense volcanic activity, leading to the formation of the early atmosphere.
It is believed that the early Earth's atmosphere likely consisted of gases like water vapor, carbon dioxide, nitrogen, and methane. Over time, as the Earth cooled and life forms evolved, the composition of the atmosphere changed due to processes like photosynthesis.
Earth's atmosphere formed around 4.5 billion years ago, shortly after the planet's formation. The early atmosphere likely consisted of gases such as hydrogen and helium, but has since evolved through volcanic activity and the presence of living organisms to the composition we see today.

Early volcanoes discharged different combinations of gases into the Earth's atmosphere creating rain, which cooled the planet and formed solid land masses, and every other element discovered presently.
