Other intelligent Lifeforms

You have to think of how our (Very far back) ancestors would look on to a computer. It would be pretty much unthinkable. The wheel was made by the smartest people then, who realized how it worked.. Now, its common sense. We will never understand how smart we will be in the years to come, unimaginable things.

I can't imagine thinking much further than other Universes, the collective imagination of the human race today is far beyond 'real' knowledge. For example, we can theorize about other Universes now, but we are never going to really know if they exist.
The difference today than 30,000 years ago, is we are a lot less fragmented, intelligent and most of all imaginative. IMO our knowledge will never succeed in filling our imagination.
