No one has still proven that life has any objective meaning. Gods remain unproven and nihilism, although not desirable, has become the most likely truth. At least from our own human perspective, it really seems like the universe has no particular use for us. Makes any arbitrary human-made purposes to life ultimately useless, especially when you're just suffering either way. It's so absurd that it's not really surprising that people hold onto blind hope with beliefs such as "god has a plan" or "I'll find happiness eventually" or just try to ignore it all and let their emotions guide them entirely.
