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.
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)

Because the Blast and radiation are considered harmful to all lifeforms on the Earth.
The earliest lifeforms on Earth were germs and bacteria, and they are very different from hat they are today because many of them have mutated and changed to fit what has happened over time. We have been able to minimize, if not eradicate, sicknesses caused by these lifeforms, and that has caused changes in them as well. Basically, they have modified themsleves to fit the environment or conditions around them. From what they were when they were first on Earth, compared to what they are now, there has been a huge change.
