Why do countries trade with each other in today's global world?

Picture the whole world as one giant kitchen, full of cooks. One cook has all the salt. Another has all the lemons. A third somehow ended up with every single egg on Earth. None of them can make a decent meal alone — so they start passing ingredients across the counter. That, in a nutshell, is why countries trade.
Here's the first big reason: no country has everything. Some places sit on oceans of oil. Others grow coffee easily but couldn't grow a banana to save their lives. The Earth handed out its gifts unevenly — a little here, a lot there — so trading is just countries swapping their lucky piles.
