There is no point to life, you make your own.
And the same goes for Minecraft. I think people who say Minecraft has no point are wrong. The point is to create the point. In other words, you make your own goals rather than have the game decide it for you. That's why I love it, it's so open-ended. There are no rules in the game of Minecraft, you do what you want and give it the purpose that best fits you. From building the best house to mining everything in site. From exploring the nearly endless worlds to fighting the enderdragon.
And even if vanilla doesn't satisfy you, or you just get bored of it like I do, then there's a ton of mods you can add in to spice up your experience in the game. I, personally, am a fan of the Attack of the B-Team mod pack on the Technic Launcher. If done right, these mods can add to the purpose and meaning that you have given the game. Or, if you're too lazy to give it meaning, you can always play one of the many adventure maps that give you a solid goal to work towards.
Honestly, how can you not love this game? Don't answer that.
