People found G-d through this thing?
well in the framing story, with the writer interviewing pi, it is said quite literally that "this story will make [the writer] believe in god" and it ends with him going "WOW WHOA, YOU WERE RIGHT" so yep, that was the INTENT of the story
even if it had functioned as intended it wouldn't have done that though, it never tells anyone why they should believe in god. it tells them, at best, "maybe your life would be better if you could just give up and believe in a pretty fairytale once in a while. why not try THE BIBLE for instance?"
I must've blocked out all the religious stuff
okay no offense, and i haven't read the book and you haven't seen the movie but wow, how is this possible when the word "god" is spoken about once every 5 minutes throughout and the whole thing is LITERALLY a fable or religious parable with the conclusion being little more than "y'all best believe in god"
that there were no animals on the boat to begin with.
well i don't know if the book makes it as blatantly clear, but yeah, the animals were never there, they were just ham-fisted one-to-one metaphors for the other surviving people in the lifeboat. cook = hyena, sailor = zebra, mother = orangutan. so you have two stories that are mostly the same, except in one it has pretty and cute animals instead of terrible evil real-life people. also suddenly there's an imagined flesh-eating island for no apparent reason.
as far as i can tell the entire message of the book/movie is that if the end result on your life is the same, why not believe in a lie? i mean wouldn't it be great to believe that the universe is a benevolent place and that there's a god looking out for you and who loves you? it's almost exactly
this shit all over again except several hundred years too late, and the author presents it as if it's some new, deep, revelatory truth
so
finally how people always believe the lie in light of the truth
well it goes further: the author actually suggests that it is PREFERABLE to believe in the lie, even when you know it is a lie, as long as the lie is more pleasant.
in that, he's completely glossing over a few facts:
1) ACTUAL religious people (not this post-modern fair-weather religion people subscribe to these days) do not believe that their religion is a lie, they believe it is the truth
2) BELIEVE IT OR NOT but there are people who think truth is preferable to lie even when the truth is not sugar-coated and pleasant
3) religion is not fluffy and pleasant
EDIT: and to elaborate on your point: you might remember that pi, the writer, and the japanese interviewers from the shipping company ALL KNOW that the lie is a lie, but they all agree it is more pleasant, so that is the version that is getting canonized, so to speak. but at no point do they actually BELIEVE that this was the chain of events that actually happened. so... yeah
