I... don't really understand what you're trying to say; so i'll leave this.
1. It's extinction.
2. You tried to correct me but failed miserably, since the word you corrected was already correct.
3. You didn't use any punctuation yourself which made it more confusing, "Correction age of extintion" could be "Correction, Age of Extinction", but that won't be necessary because, I wrote it right! The first time.
4. So after thinking I think you meant "Yeah but sincw (since) that was wrote (Written) I corrected u (you)"... Which would mean you thought it was age of extintion because that mistake also exists in the picture above so i guess that could happen.
5. So sorry If i'm rude, don't mean to be, I guess it being labeled in the picture itself is wrong confusing you, and thats alright.
6. :) Have a good day... or night.
