What exactly is it you and the Qu'ran are trying to say? Are you trying to sayThe thread isn't for discussing the phenomenon and whether if it was known longtime ago since the stone age or on modern days but it is to show how Dawkins lied about the 2 seas that don't mix and twisted it that the quran says that the salt water and freshwater don't mix and then he asked to try to mix 2 glasses of water to see that it mix,but that isn't the case for the 2 seas except if as you said it takes long time for the 2 seas to be mixed, eventually,maybe millions of years like the story of evolution.
1. When the two seas meet, not a single molecule of water from one sea can ever come close to a single molecule of water from the other sea because there's a barrier between them?
2. Or are you trying to say that there will never come a time when every single water molecule from one original sea is next to a single water molecule from the other original sea?
