"We have no such evidence that China existed before the Flood."
Some of the ancient Chinese writings were discovered, by archaeologists/historians, to be as early as 8,000 BCE. Way before the supposed 6,000 years that YECers claim this planet was 'created'.
So it's not just Kitzmiller vs. Dover that annihilates your argument - and thus your 'beliefs' - biologically.
PROTIP: There are ancient Chinese writings from during the supposed 'Flood'. Nope, no records of a supposed civilisation-destroying cataclysmic event. And the ancient Chinese were sticklers for record-keeping; it's the reason why said archaeologists & historians know so much about them (as they do, re. the ancient Romans, Greeks, Egyptians, Babylonians, Sumerians etc.
And yet, your so-called 'Bible' doesn't give the exact, precise, detailed information, facts, based on evidence we need. Funny, that, and not in a 'funny-ha-ha' way, neither.
Why, it's as if... the Bible was written by nothing more than Bronze Age goatfuckers with ideas above their station...? At least we know that much about them, to say nothing of it's fundie, Literalist believers: Ignorant and Illiterate.
Moral: The Bible. It does the thinking for you. Meanwhile, the phrase 'Inquiring minds need to know'. It exists for a reason. And there's the key word: 'Reason'. Because the Bible - and it's unjustifiable 'beliefs' based on such - has none whatsoever.
