Many people have posted threads asking what a world would be like without Christianity, or Islam, or perhaps even a world without Abrahamic Religions entirely. Obviously, PODs that occur centuries or millennia before the birth of the Buddha will obviously butterfly away Buddhism if the said POD is in Eurasia. Nonetheless, I am positing that POD itself would be that Siddhartha Gautama is just never born. Obviously, this would butterfly away many South Asian and East Asian cultural and philosophical developments, but how would it affect the world of the Greeks and the rest of Classical Western World. I'm not sure that the butterflies would reach Europe until a few hundred years later. What would Europe and the Near East even be like?
Another question I have to ask is "would someone else have taken Siddhartha's role as a TTL Buddha". Sramanic traditions had already existed for some time during the life of Siddhartha. Jainism is already a thing by this time and perhaps Jainism gains more traction outside of India?
Lastly, would there be greater cultural interplay between Greater Iran and India? What about China.
P.S. I know Schopenhauer's philosophy would be butterflied not only because of the POD would be millennia before his birth, but his philosophy was very much influenced by Buddhist thought. I might be wrong in saying so, but please let me know.
