What a joke. Life on earth spends millions of years evolving until by chance it creates sentient life capable of producing a civilisation with the potential to colonise other planets, but the sun bellows into a red giant and destroys it and all evidence of it's existence.

Oh well. Easy come easy go.

In the time it takes this to happen we'd have made great advancements nevertheless. If the entire human race manages to die and nothing is left we can still appreciate what we have now and what we theorize might be created to presently be able to remember by our own species how significant we really are.
