Well if Darwin's theory is correct, which I think we all can agree to the most part it is, then our brain evolved thousands of years ago to our needs.
This theory could also suggest ET involvement.

So why was our brain developed far in advance of our needs? Smart enough for Space Travel.

Our brains evolved thousands maybe millions of years ago and our inteligence is proof.

Some scientists for decades have advanced the hypothesis that millions of years ago, human ancestors began walking upright because it used less energy than quadrupedal walking, gaining advantages in things like food foraging.

I would think that if an outside force was involved, we'd see a rapid development... as we've seen with dog breeds. 600 years ago there were no poodles or pugs or doberman pinscers or german shepherds... those breeds have all been created in the last 500 or 400 years. It didn't take 4 million years for a rottweiler to evolve from the Basic Dog.
So the long time period shows that natural selection was in progress and not some outside force.

I would say 6,000 years of human development from carving stones to sending car to Mars is really really RAPID.

You're way underestimating the amount of thinking and reasoning that apes can do. They're second only in intelligence to humans and can learn to do all sorts of things... including how to pick locks to let themselves out of cages! In the wild, they use tools... and there's the big difference.
I believe you've got it backwards -- we can travel to space because our brain was larger.
You've also underestimated the impact that our hands have on intelligence and changes in the brain. No other animal has hands like ours -- they have similar hands, but these hands can't work a screwdriver like ours can and they can't do tiny and accurate movements (like repair eyeglasses.) When humans began to use tools, we saw more changes occurring in the species.
Uhmmm... life's been around for billions of years and the pattern for brains has been evolving for about 4 billion years. The dinosaur brains had much the same parts (but kind of "strung out" as your brain has... and many areas weren't very thick.)
Hominids emerged from something that was apelike and had a big brain for its size (Proconsol) about 5 million years ago. As we moved into becoming tool and fire users, brains changed (and bodies became more adapted to walking on 2 feet instead of all fours.) Modern brain-sizes start occurring about 60,000 years ago.
earth2 : "This theory could also suggest ET involvement."
Byrd : How so?

For 5,900 of those years we were using horse and carts, and writing messages on stone or paper. In the last 100 we went from horse and cart to landing on the Moon, from stone and paper to sending messages invisibly through the air ...
If there was any extraterrestrial involvement that it must have been in the past 100 years .......

Aha this makes sense.
That could also bring Roswell theory to truth. It was in 1950s something, and 10 years later human shot rocket to moon, and now to Mars.

Personally, i am of the opinion that we did not not originate here. Not in the way we assume. I believe we migrated here from somewhere else, and "fell" so to speak.
