Ok, I won't bother you with the facts, since your raving moonbat mind is already made up.
In one aspect you are correct, though not for the reasons that you think.
The Saturn V can't be built today, much like the Giza pyramids can't be built today, nor could another Panama canal be built today. None of them for lack of technology. All of them can't be built today for two reasons. One, there is no need and two, since there is no need, no one would spend the money necessary to do so.
Done correctly, "There are none so blind as those who will not see".
Actually, give me a shovel and I will dig a canal, the Pyramids are excellent, and it still remains I just started this to see what people think the monitor took out the phrase for shits and giggles.
