Knowing the right distances would be extremely important for them. Columbus thought the world map looked like this, which is why he set out on his trip and why almost everyone in Portugal and Spain (rightfully) thought he was an idiot. He got lucky there was an entire continent between Europe and Asia.
Lol I love comments like this. What in the world are you going on about? Could you add just a little bit more so it makes a proper copy-pasta? You've got a great off topic unhinged rant but, in my opinion, it is just a touch too concise for dumping into shitposts. I think one more paragraph would set you up, two if you're in an overachieving mood today.
