Many of us spend our lives thinking of science and philosophy. Looking for answers to the meaning of life the universe and our place in it. And then eventually we die. Have we not accomplished anything? Does our knowledge somehow live on beyond death? What is the point of seeking knowledge?
You would have died in early childhood had you not sought knowledge, but fortunately knowledge-seeking in inbuilt and needs no justification.
Edit to add: This reminds me of a poem from Cat’s Cradle:
That’s awesome. I like it.
