Knowledge: The Roman Empire first used testum in 300 BC to bake while the Egyptians, the foundation of the bakery, invented bread before anyone else.

Conversation:
I love going to the bakery and seeing the baker cook stuff. Do you know any cool stuff about bakers?
Grains have been a staple food for a millennia, baking is a very old activity.
Thats neat, I bet that baking has a very long heritage, Did people in the stone age know how to bake food?
I'm not aware of the info of baking during the stone age, but during the 5th and 6th century BCE, the ancient Greek communities had a communal oven to bake bread in and enclosed ovens.
wow the greeks had ovens? thats really cool. What kind of ovens did they use? Was it coal or fire?
Their enclosed ovens were heated through wood fires.
That makes sense, since wood is easily available. But who started the baking first? They deserve a noble prize!

Response: I can only tell you what is written and available so apparently the Egyptians, the foundation of the bakery, invented bread before anyone else.
