A) The Hadean was characterized by extreme heat, radiation, and frequent asteroid impacts
B) Fossil evidence of this life form has been found in Hadean rocks
C) The Hadean had conditions suitable for this life form to thrive
D) The Hadean had an abundance of oxygen and water

Answer 1

During the Hadean, extreme heat, radiation, and frequent asteroid impacts made it unlikely for life forms to exist. The Hadean also had strong radiation and volcanic activity. The first organisms on Earth were likely able to survive in harsh conditions.

Step-by-step explanation:

A scientist can assume that this life form did not exist during the Hadean because The Hadean was characterized by extreme heat, radiation, and frequent asteroid impacts. Before the atmosphere became oxygenated, the planet was subjected to strong radiation and volcanic activity. The first organisms that appeared on Earth likely were able to withstand harsh conditions.
