ELI5: Why do counties have different names in different languages?

Example: Deutschland is Germany in English. Why dosnt everyone just call a country by the name it gives itself?

Translation into other languages, including mispronunciation and physical inability to pronounce certain sounds. 

1) Translation: countries like the United States are just words. You can directly translate them into a different language. In Spanish, it's Estados Unidos. The words just happen to have pretty direct translations. 

2) Mispronunciation: Turkey in Turkish is pronounced probably closer to the spelling Turkia. It's not that hard for an English speaker to try saying. But they didn't. Keep in mind, too, that country names can be very old. So at some point, the mispronunciation is simply the way you say it in that language.

3) Inability to pronounce certain sounds: language is interesting. We're born being *able* to learn and produce all phonetic sounds of any language. But at a very young age, you lose your ability to say sounds that aren't familiar. 

In English, R and L are very different. In Japanese, they're very similar. You actually lose the ability to even *hear* the difference if you aren't exposed to it as a child. In Hindi, there are 3 different ways to pronounce the letter D. It's really hard as an English speaker to even tell any difference between them. And this is proven by experiment: if you slowly transition an R to an L step by step with computer programs, English speakers have a clearer threshold where R becomes L. Japanese speakers have a lot harder time having a consistent threshold of detecting which is which. Same thing for English speakers and the D's.
