I absolutely love this question. I'll offer my opinion, but I always say take other people's answers, including mine, with a grain of salt.
From a natural perspective, and as DonGorgon said, the basic point is to perpetuate the species...but we have so much time in our lives, and the power to choose what to do with it, so I believe there's more to it than just that. Also, that's just plain boring to me, so I choose to squeeze out more.
Taking it past the biological imperative, the point of life is whatever you want it to be. People will try to tell you how to live your life, but the fact is, if you take a look around, NO ONE actually knows what's going on here. NO ONE!!! Some people have more experience and wisdom than others, but no one knows what this crazy experiment called life really is. We're just thrown into this world where countless people will claim to have truths and "the way", but it all comes down to what you want it to be. You can do pretty much anything.
Do you want to be an agent for change against what you consider injustices?
Do you want to indulge in every pleasure possible, and focus your life around them? Drugs? Sex?
Do you want to run rampant and make people's lives miserable?
Do you want to be a source of positivity for everyone you meet?
Do you want to be a cynic, be lazy, and throw blame around for your misgivings?
I mean, you can literally do anything. Ultimately, I want to live to make my life, and the lives of others around me more enjoyable, because I believe enjoying this crazy process of life is one of its greatest purposes. It sounds like you're beginning to question what exactly is going on here, but that's a great thing. A life without questioning and reflection is a life not worth living.
