A two-minute review of his Wikipedia page would answer your question (or ad-hominem attack). If you looking for inventions, he designed and built the first web browser and the first web server[1]. If you're criticising him for building on top of what others did, no man is an island. He did improve on what was already there. Why not read the details for yourself?[2].
