The Hadean Eon, the earliest time interval, was when the Earth was cooling, and continents and oceans formed. Lifeforms are thought to have appeared in the following eon, the Archean Eon.
(eras are a much smaller time interval, and the Hadean is not normally subdivided into these)
The earliest lifeforms on Earth were likely single-celled organisms, such as bacteria and archaea. These organisms were simple in structure and relied on primitive forms of metabolism to survive. Over time, they evolved into more complex life forms.

Cenozoic era
No, the Cambrian explosion was not a volcanic eruption. It was a period of rapid diversification of multicellular lifeforms that occurred around 541 million years ago, marking the beginning of the Paleozoic era.
The current era is the Cenozoic. It began 65.5 million years ago. The previous era was the Mesozoic.

Because the Blast and radiation are considered harmful to all lifeforms on the Earth.
Lifeforms was created on 1994-05-27.
Lifeforms - song - was created in 1994.

The era in which Earth was the hottest was called the Archaean era. This was when the ocean temperatures were above 100 degrees.

No. Evolution is the process whereby lifeforms diversify. The Earth, along with the rest of the solar system, was created by the aggregation of interstellar debris and gases into a protoplanetary disc.
Cenozoic era
Earth is currently in the Cenozoic Era of the Phanerozoic Eon.
The beginning of Earth's current era is marked by a mass extinction.
