Final answer:
The claim that Pyrrho was the first to suggest that notions about gods were culturally shaped is false; it was Xenophanes who first articulated this idea.
Step-by-step explanation:
The statement that Pyrrho was the first ancient Greek philosopher who argued notions about gods were culturally shaped is false. The pre-Socratic Greek philosopher who is credited with originating the idea that the gods are projections of the human mind and that the Greeks anthropomorphized divinity is Xenophanes. Xenophanes was interested in the rational basis of religion and was among the first to articulate the notion that people's conceptions of the gods reflect their own characteristics. His ideas predate Pyrrho and represent early philosophical challenges to traditional religious beliefs, pointing towards a more rational understanding of divinity.
