The world is covered with oceans of knowledge and of course water!! many learned men have come and gone but have they really learned it all? i don't think so humans are advancing upgrading,updating,inventing but did they invent flying cars? teleporters,talking mirrors? NO we still have a lot to learn and in the ocean of knowledge a whole lifetime's work is just a drop in the ocean nobody can learn everything not in a 100 lifetimes because there is no end it's not like a book if it had an ending it'd be finished by billions of people but in order to gain all the knowledge we humans might have to stop progressing and in this fast life if we stop we might come to a halt permanently we want to know everything sometimes we need to know everything and at times we have to know everything but you gotta face the truth accept the facts and stop trying so hard because no matter what we can't learn it all
