There are 636 million square feet in Manhattan. There are nearly 8 billion people on Earth. So, no, you're wrong.

EVEN IF YOU WERE RIGHT, you'd still be wrong, because we all need more than just the space we stand on. It takes acres and acres of space to produce your food and water and clothing and TVs and your phones and your sofas and your silverware and your car and your power drill ... need I go on? Stop saying ridiculous and untrue things, please.
