What was the first invention by man?

Answer 1

The first invention by "man" was actually created by our ancestors, either Australopithecus, H. habilis, or H. ergaster. It was probably a wooden scraper or wooden chopping device that was first used more than 2.6 million years ago. However, wooden tools decay over time, so none exist for archaeologists to examine. The oldest inventions which we have clear evidence of are Oldowan stone tools from East Africa dated to approximately 2.6 million years ago.

Although both controlled fire and the wheel are often cited as the earliest inventions, the first evidence of fire occurs around 400,000 years ago (although possibly as far back as 1.7 million years ago), while the wheel was not invented any earlier than 10,000 BCE.
