Final answer:
The ancient Greeks perceived their gods as immortal beings with human-like qualities, sometimes helpful, sometimes indifferent, but not as cruel overlords or micromanagers of human existence. Thus, the most fitting answer is that they regarded some gods as helpful to humans and others as indifferent.
Step-by-step explanation:
The ancient Greeks had a complex relationship with their gods, seeing them as possessing both positive and negative human-like qualities. The Greek gods were immortal beings who could be moral or immoral, and their actions could be petty or just. In the realm of Greek humanism, the gods were not regarded as cruel overlords aiming to make humans miserable; rather, they carried the spark of godlike creativity, and while sacrifices and oracles were part of Greek life, the humanistic view suggested that if the gods existed, they did not seem overly concerned with human actions.
Contrastingly, in Mesopotamian beliefs, the gods were viewed as cruel and capricious, with humans created to serve and appease the gods or face their wrath. Thus, the correct answer to the student's question, considering the provided information and options, would be Option A: The ancient Greeks regarded some gods as helpful to humans and others as indifferent, rather than as selfish, cruel, or controllers of every aspect of human life.
