Indeed there is no final purpose because we will all die at the end. But I see it this way:
1. I have always thought that asking the question "Are humans here for a reason? If yes, what is that reason?" is very egocentric. Why do we ask that question in the first place? Because we are giving humanity an inherent value that it actually doesnt have.
2. Something doesnt have to be eternal to have value. This why our lives have value and leaving a legacy to future generations has value too.
3. And finally, humanity belongs to the universe. So whatever happens to humanity molds the universe in some way. Does it matter? No, but at least we changed the cosmos, somehow.
