There is no point to life?

I've been thinking a lot and I find that we are born, live and then die. And then when you die anything that you did on Earth doesn't matter. Nothing will be remembered. It's gotten me thinking that there is no point in life. Yes everyone says you have to find a purpose, but then when you die that purpose is nothing. So why even bother try hard to do all of these things if they mean nothing in the end? Everything dies in the end. Memories, friends, family, love etc. It means nothing. Life is nothing.
