1. The world "looks" very old becuase the things that we refer to as signs of age are neccesary for a fully functional ecosystem. I.e. you can't have catfish without having an "old" stream.
That's simply untrue; there’s no reason for 4+ billion years of radioactive decay to have taken place, there’s no need for there to be a 50,000+ year record of algal blooms in the varves of Lake Suigetsu, and there’s no reason for geological formations such as angular unconformities. None of these phenomena are required to form a fully functional ecosystem and they are just the first off the top of my head.
2. They have built wooden boats bigger than the ark. If is it watertight and made of wood, it will float. You can even make a boat using concrete.
Again, that’s simply untrue. No one has built a boat made only of wood as massive as the ark is supposed to have been, and if someone could they doubtless would soon discover that you need to defy simple physics to make it “watertight” as anything that big will be susceptible to hogging and sagging in water that’s anything but completely smooth. Take the example of the six-masted schooner, the Wyoming, built out of wood and with the benefit of things Noah wouldn’t have had like steel and 20th century building techniques.
The Wyoming was a wooden six-mastedschooner, the largest wooden schooner ever built. She was built and completed in 1909 by the firm of Percy & Small in Bath, Maine.[1] TheWyoming was also one of the largest wooden ships ever built, the longest wooden ship ever built, 450 ft (140 m) from jibboom tip to spankerboom tip, and the last six-mast schooner built on the east coast of the US.
Because of the extreme length of the Wyomingand its wood construction, it tended to flex in heavy seas, which would cause the long planks to twist and buckle, thereby allowing sea water to intrude into the hold (see Hogging and sagging). The Wyoming had to use pumps to keep its hold relatively free of water. In March 1924, it foundered in heavy seas and sank with the loss of all hands.

3. You are probably looking at proto-species. I.e. one canine species, one feline species, etc.
“Proto-species”? Regardless of made up terms, the genetic bottleneck we would see if all animals had been reduced to a single mating pair 6,000 years ago does not exist. Calling them different names will not change that.
4. The 4000 year issue isn't really a problem. It is easy for the Biblical timeline for the flood to be pre-civilization.

Except that we have copious evidence of civilizations that go back further than 4,000 years that weren’t wiped out by a global flood. Here's some things that were happening around the world apparently while the flood was occurring who apparently failed to either drown or even notice that the entire world was covered with water,
