Hey Chobots!

I have another puzzle for you!

Look at the image. You think it is a funny smile, don't you? :)

Well... It may look like, but it is a very very old Earth symbol (I mean it... It is really old), representing something really really important. Will you find out what?

I will take care about monthly citizen pass for the winner who writes the first correct comment!
