I will not enter in this debate,
You just did with your statement just before that.

there are too much proof in both side,
Like what?
There are some people who will doubt anything.
Back in the '60s/'70s, analog TV quality was always suspect.
Today, we have CGI and other capabilities, so even the highest definition would not be trusted.
Of course, those who actually use optical scopes to track objects in low-earth orbit (LEO) know the truth.
Then it's just a matter of boosting another 10Kph to geostationary.
Boeing just launched the heaviest geostationary object when they put up the latest DirecTV sat earlier this year.
It's only a little bit more to half-way to the moon.
As far as astronaut survivability, it's simple pressure.
Vacuums aren't that hard to deal with, when it's on the outside.
And putting astronaunts in space for a week, not difficult at all.

I just think we weren't technologicaly able to do this back in '69,
In actuality, we've had the technology since near the beginning of the 20th century.
It was just lack of practice until we poured billions of dollars into it.
The military had successfully used mechanical and analog computers, perfected hydrolics and countless other systems by World War II.
[ SIDE NOTE: In fact, one could argue that we didn't need a digital computer in the Apollo program. ]
And that included the ballistic launch vehicle that could approach the speed for escape velocity.
So then it started with our ballistic missiles for military offense and went from there.
In fact, it was the chronic and nearsightedness to of NASA's predecessor to disallow use of military launch systems.
That quickly changed when we (the US) fell well behind the Soviets in lift capability.
Our first early shots couldn't even break escape velocity while the Russians were almost capable of launching a space station.
From there, it was a lot of people doing a lot of things at a very, very expensive rate.
All the efforts of a nation once focused on winning a war put right into winning the space race.
It's amazing what can be accomplished in only 10 years when you have the technical capability, but just lack the technical repeatability.
Ironically enough, despite the 2 Shuttle Transport System (STS) trajedies, it's been an unbelievable success and NASA's greatest achievement.
Mercury, Gemini and Apollo were sub-5 year programs -- use and lose.
The STS has been an engineering feat in the pure reality that it has been able to sustain a system of a 100,000 part bill-of-materials (BOM) 25+ years.
In fact, both trajedies were more about change in materials, and failures of material reviews (MRs) -- e.g., the sealant change on the O-Rings in 1986, and the banning of CFC syrofoam in 1997+ -- than anything else.
That's what happens over time with loss of mindshare (engineers leaving or just dying of old age), trying to track supplier changes, etc...

and today it should still be very very hard to do it.
At the budget NASA has today, I very much agree.
Furthermore, STS is clearly designed for Low Earth Orbit (LEO) launch, and not a very good platform for higher boost -- despite the original promises.
God knows the STS was more about what the US intelligence services and military wanted than commercial interests.
But it's really just a matter of money, time and payload you want to send.
The moon is not far away at all, once you can hit geostationary, then you're literally half-way there.
So then it's all about weight.
Now Mars would be a completely different scenario.
Mars is a crapload more difficult than the moon.
I honestly think that sending men back to the moon would be safer, cheaper and more fruitful than going to Mars.
At least for the next 50 years.
Our focus should be establishing gravation-neutral installations (the so-called "L" areas between the Earth-moon where there is no additional gravitation pull except for the norminal orbit around the sun),
as well as see what we can accomplish with a moon base.
As much as I know President Bush believes a lofty goal like Mars would boost the American pride, let's be realistic, it's not in our feasible interest for our future.
Just like the moon really wasn't either at the time we did it -- we went for the edge of the playground, but now we're still back, stuck in the sandbox.
