Yeah, if humans were special, why weren't they Gold based or Platinum group based or Titanium based or Aluminium based ? Now, that would have been special. Instead, humans are carbon based. Just like the rest of life on earth.
I would say the problem with your, "challenge" is that it is much less of a challenge to take two primates with a very similar body plan and say, "show me how it can't be micro".
Well it's always rhetorical to compare apples to oranges then say apples are the same as oranges.
The only thing we share with "flat earthers" is that we have arguments to the contrary of a popular claim.
It's a generalisation fallacy to say "you're no different from a flat earther". Did you know the members of flat-earth society are evolutionist? At least some of them are.
Of course, but all members of the flat earthers and YEC's and all creationists and evolutionists and all other people have the same thing in common. All of them. They're all carbon-based.
