Questions I have concerning the story of Noah's Ark

So this article is not meant to offend anyone. These are genuine questions/discrepancies i have noticed in the story of Noah & the flood. Please answer if you can or get a laugh out of it.

(It was a long church service & I had plenty of time to think)

So here are we go:

1. How did the Egyptians need an entire army of slaves to build the pyramids, but Noah just needed his three sons to build the ark?

2. Where did Noah find enough wood in the Middle East to build a ship of that size?

3. How did eight people take care for all those animals?

4. Why did God have to kill off all but two of every living creatures?
   And how did He decide which ones made the cut? I mean, what did those other llamas ever do to Him?
   

5. Where did all the water go after the flood? Other civilizations that lived in the same time period as when creationists believe the flood actually happened. So, how come in all of their recorded history & all of their documentation that we have, doesn't have any mention of this global flood?

6. The Bible says there were no rainbows before the flood. But that would mean that there was no sun, no rain or no phisics. So, which is it?

7. Because we have evidence of dinosaur fossils, we know dinosaurs had to have been on that ark, too. How did they fit in there?

8. Did the animals go to the bathroom at all during the year long journey? And if so, where did it all go?

9. How did Noah's family not get all sorts of diseases given that there had to have been like huge piles of shit building up on the ark?

10. How did Noah collect the tens of millions of insect species alone, especially when a lot of those species don't live anywhere close to each other geographically?

11. Who inspected the insects to make sure you had one male and one female?

12. How did they get the penguins from Antarctica and the koalas from Australia to come to the Middle East? And after, how did those animals get back there?
    

13. Which animals on the ark had lice? Were they only two lice?

14. What about gonorrhea? Which family member brought that along for the ride?
    

15. How did ants survive? I mean, they need a whole group of them to survive together, because they all have specialized tasks. It's not like two of them can just hang out on the boat by themselves just waiting for a year to procreate. It doesn't work like that.

16. Genetically speaking, how is it possible that we have all this human diversity that we see today, if we just started out with Noah's family a few thousand years ago? Natural selection doesn't work that quickly. .
