My story has NEVER changed, your inability to comprehend seems NEVER changing.<quoted text>
You changed your story, but still didn't get it right.
As far as science before DNA was discovered, they did not know, or could not demonstrate its existence.
They did not conclude nonexistence.
You can't even get it right when I help you.
You really do love to play with words to suit your argument, in this case it's a way for you to cover your reading comprehension error. Nice, dishonest, but nice try.
"They could NOt demonstrate its existence so they DID NOT conclude it was nonexistent" Is this the same way science does NOT conclude that pixie dust is nonexistent? Or that "Never Neverland is also nonexistent?
I do believe you have won the topix prize for having the most posts where adding and deleting words gives YOU and only YOU the impression of wining your point. First prize........You get to strap on a pair of hockey skates and see if you can last 60 seconds with an enforcer, you can even pick the team. LOL
