What do the artifacts tell us about the lives of early humans?

When the Archaeology finds the bones or artifacts they can have the cule what did early humans did and how did they leave. Some artifacts prove that the early humans how looks like and some tells that the animals looks same as nowadays.  We even know that early hymans eat and what did they make and we even know what did they did when they were getting smarter.

The early humans made the tools and the Handy Man made really simple tools. But when they got smarter they made Speer Thrower. I think the invited that Speer Thrower because they want to hunt safely. They even draw some mystery drawings. We need to find out why did they do.
