The Wikipedia link mentions that: “Astronomer Carl Sagan quoted it in discussing India's "tradition of skeptical questioning and unselfconscious humility before the great cosmic mysteries."”
The quoted text just says "We don't know. Hypothetical beings higher than us don't know because they came after the initial origin. A hypothetical creator might or might not know."
I agree with the first sentence but it doesn't give any insight really. The reasoning regarding Gods coming after creation so they wouldn't know doesn't check out. Maybe they are great scientists and found a way to get the answer? By implying even Gods don't know you get defeatism - how could we mere mortals know? Let's not try.
