Ken Ham's Ark-replica is damn big... which yields even more questions.
http://www.rawstory.com/2016/04/sneak-peek-ken-ham-thinks-this-fake-dinosaur-on-noahs-ark-will-convince-you-to-trust-gods-word/The completed ark will be about 450 feet long and 150 feet wide, and it stands about eight stories high.
...
The creationist said the ark — which will be the largest timber structure in the world when it’s completed — is a “jaw-dropping experience” for visitors who have been able to see it already.
...
There will be 132 exhibits on three decks at the completed Ark Encounters, which seem focused primarily on proving two of every land animal could have fit on the biblical watercraft in an effort to “teach us to trust God’s Word.”

The Eiffel-tower is estimated to weigh 10,000 tons. Let's say that Noah indeed was super-intelligent and had super-technology that has since been lost, but...
1. Where did Noah get 1000 tons of wood? And we are not talking scrappy fire-wood. We are talking straight-grown timber you can cut into planks! In Judea!
2. How did he get that timber? Did he cut it himself? Did he buy it? Where did he get the money from? Howdid he transport that timber to the construction-site?
3. How much moss, fat and tar did it take to make that ship water-proof?
4. Where is the center-of-mass of the ship? How deep did it lay in the water? How did the Ark behave in a thunderstorm at sea? IIRC the Ark had no steering-mechanism. So what if a heavy wave happened to hit the Ark from the side?
5. How did the crew of the Ark get rid of the rain and seawater that spilled on top and inside the Ark?
And while we are at it:
- If that super-technology existed, why did people still fight with bronze-weapons? Why was such a simple technology as horse-chariots still rare? Why was there even the need for slavery? How come the Bible doesn't mention other people using that technology to build something?
- How many tons of food were needed to supply the animals for IIRC 40 days? Where and how where they stored on the Ark to prevent it from spoiling on a humid wooden ship?
- How many tons of shit did those animals produce? What system was used to clean their cages and how many people did it take to shovel all that shit?
- How much drinking-water was needed for those 40 days, how was it stored, how was it prevented from spoiling on a wooden ship full of people and animals, how was rainwater harvested, and how was the water distributed? The Ark was 450 feet long. Did people run back and forth 200 feet with 2 buckets of water each all day long?

Did you know that Star Wars actually happened?
I can prove it!
All I need to do is build a replica of an X-Wing.
I won't use the correct technology or the correct material and I will make wild guesses how the interior actually looks, and of course the replica will in no way perform similar to the original.
But the mere fact that it's possible to build something that looks like an X-Wing will be prove that all of Star Wars is true.

The increased diameter makes it take longer to rotate. 
And it supposedly just evaporated and collected where? Space?
You're not supposed to use "facts". That's just not fair! 
Just run down to the local Manger Depot and place an order for the number of cubits needed.
They's contract out to the loggers in the Sahara Forest to cut to order, then have it go out by ship.
(Some will probably claim that the Sahara is a desert. Well, yeah, NOW it is - after they cut down all of the trees to make the freaking ark!)
...would that suffice?
...without a functional Light-Saber.
But if you were to gimme a green kick-ass light-stick of awesomeness then I'd be all there suckus'
...why an arc?
If you need all that magic to keep the lions from eating the gazelles for forty days why not just grow a mountain where all the animals can live above the flood. Make a magical Doors of Durin that only Noah, and his soon-to-be incestuous ilk, can pass through to get to the mountain.
Easy-peasy, no Sahara Forest™ required.
Then again, why were the Cetacea (whales), Craniata (fishes) and Cephalopoda (Octpodes) all exempt from god's wrath? (Not to mention the bacteria and viruses.)
Have you ever seen coral and or salmon spawn? Ewweww.
