Who are the brightest of the bright?

You want names? Hmm...I'm a little short on those, BUT I have some ideas.

!. Find the cave man who discovered that one+one=two.

2. Find the next cave man who equated speech to markings left in the dirt, for the sake of leaving messages.

3. Find the cave man who discovered recurring patterns in nature...who then dicovered them in the heavens...

Let's face it, only humans can do this, and everything we've built was done so on their work.
