Human knowledge is an accumulation which builds upon previous knowledge. It's like a pyramid. Without the previous knowledge, even Einstein wouldn't have come up with his theories. If Einstein had been born and raised in a mud hut deep in the Amazon, he'd still be smart would how could he possibly think of his theories about math and physics if all the math and physics he knew about involved making huts, canoes and spears?
There's a reason why the burning of the Library of Alexandria was considered a tragedy for all humankind. Lots of knowledge there even if mostly history.
