Hinduism it's pretty much alive, and Christianity it's just a fork of Judaism.
When Cristianity didn't even exist, the Chinese already had a good chunk of philosophy perfectly set and written, and even modernish rules for war and diplomacy: Tao Te King, and The Art of War.
Heck, America from Canada to the Patagonia didn't even know about Jesus until the Europeans arrived 1500 years later. 1500s damn years.
For a huge continent mass spread over from almost the North Pole to the South pole.
So much for an 'Universal' God. So universal that Aquinas had to rip a good chunk of Greek philosophy to adapt (more like smash it down with nails and duct tape) ancient Middle East fairy tales into the less-desert bound Europe as the modern Christian canonical sources.
If any, the Western world is shaped by the Roman architecture and law, and the Greek worldview, mindset and math.
I am not neither a hindu or jew. Christianism in Europe is larguely cultural, our values shifted a lot
since the Enlightenment times. The US, not much, they have a large sense of prudeness which affected even policitically left leaned people.
I mean, here people it's Christian by name only. Technically, even the Southern Spain with infamous street parades with large walks carrying a big structure with a Virgin, most of that it's just a showoff and a way to say "look how loaded we are, so much that we can build great golden clothes for our Virgin".
If any, lots of lore in Europe it's just paganism with a Christian disguise.
Even Christianism itself it's so-so Christian-wannabe unlike the original one which came from the Middle East; it was largely repurposed with Greek values so people here could assimilate better these alien customs such as not being able to eat pork or nonsense about alcohol when the risk of dehidrating in Europe was near nil.
Kinda like North Korea with Communism. Marxist? Today, in name, maybe. Because Juche it's almost a copycat of right wing fascism with Asian features. Kinda like the Japanese one, but with Koreans.
Christianity is, and is still influencing our world, like I wrote above.
