Ate With Chopsticks

How did the first person on earth know how to..speak? like even think in general. Did they just think,,,,,pictures? That makes no sense but how was a language even created? How did people communicate with each other before they knew how to speak a language?????

I just download HelloTalk right now cause I was bored and it’s so awkward. It’s similar to tinder but instead of finding a future lover, you find yourself a person to teach you a language. The thing is I had to start multiple conversations which I’ve never done irl. Haha sad right ... but anyways I was talking to this boy and he asked if he could see a pic of me. Of course I didn’t send no picture cause I know not to send pics to some rando person yk.
I was just shaking that moment and then sent him a pic of my cat

Anyways, I basically made this question to hear other peoples experience from this app. And if you don’t then let’s enjoy the show shall we ;)
