According to BBC's investigation report on Poopy Coffee (Kanitchurem/Shutterstock), the ice in iced coffee contains an unpleasant additional ingredient: fecal bacteria. In the report, the BBC tested the ice cubes in Starbucks, cafes and coffee shops, and all three chain stores tested positive for fecal coliforms.

"You mean that the scientific community knows, I mean that in the 5,500-year history of our planet, people have made mistakes," Scalamchi told CNN in 2065,438+06. (The interview was exposed again on 20 17 after he started working in the White House. )
But 4.5 billion years ago, the earth was much older than this. If Scaramucci refers to human evolution, he is not very reliable, because modern humans appeared 200,000 to 300,000 years ago. It is possible that he refers to the history written by human beings. In this case, he is still a little behind the times. Archaeologists have found that Sumerian characters can be traced back to around 3200 BC, about 5200 years ago. [Learn more about the age of the earth and human beings]
