Scientifically speaking every animal is just born for the sake of being born. It's called continuation of a species. Other animals do not have a special purpose (aside from maintaining the balance of food chain and maintaining the atmosphere of earth) so how can humans be exceptions? I get it, we are evolved in some aspects (like intelligence and immunity) but that doesn't mean we are divine or there's some higher power that organized all this. Our professor ended the lecture when I asked the question (yes it happened) "Sir, what about climate change? Does that affect the interglacial period?" and he said, "We have millions and millions of galaxies with their own solar systems. It's impossible for man to fully affect nature even in earth. It's very complicated, earth is just a tiny dot in the vast space of existence." So yes there IS some evidence for "purpose in life" but that is centuries away to be discovered. I find it strange that we haven't discovered life in anywhere other than earth. So yes, it's plausible, but due to personal experience , I wouldn't find myself changing my opinion from the fact that life is pointless. Just like the universe. I may sound cruel, but universe is universe for the sake of being itself.

Now I am no post-doc research fellow in some interdisciplinary science research institute, but I shared my opinion anyway. Chemistry and biology and geology are very fun to say at least.
