I also want to take this opportunity to talk about cakkavāla. If this refers to a planetary system, it would be insane for someone to know this 2500 years ago without a telescope. But does it actually refer to a planetary system? The suttas that I’ve read which discuss the cosmos say that our sun, earth and the moon make up a cakkavāla. Then there are categorizations of a 1000 such systems, 10,000, million and even billions of cakkavāla. This can be interpreted as a collection of planetary systems but the suttas do not mention other planets.
This thought came to me after I saw many religious zealots on the internet claiming that their religious texts contain scientific facts that modern science is only just discovering. For example, many Muslims claim that the Quran accurately describes the formation of human embryo. But if you analyze the details, the similarities are only superficial. The bones form way later than the Quran claims as described by embryogenesis. I noticed similar issues with Hinduism. Some Hindus told me that the Vedas describes the distance of the earth to the sun and even the speed of light, but I found out that these people lie and make up numbers for the term “yojana” to make it consistent with the discoveries of Science. Just left this input here because I think we should not be like these people.
