Look, I am not a Christian, I have no dog in this fight. However, if you think that this is the only "mistake" or "incorrect claim" that evolutionists have made over the years you need to do some study. The claims of evolutionists are full of mistakes, incorrect labeling etc. This is just one of many. Anytime someone digs up an extinct primate of any kind it is hailed as a link to humans. So far most of them have been exposed as fraud. The French exposed even Lucy(back about 1990 or so, forget the exact date) as being an extinct Chimpanzee and not a link to humans at all.
If you are going to fight against creationists you need to come up with a more plausible argument than that this is a "single" incident of mistaken identity.
Is that what I said?

You're not very good at reading comprehension either.
