Again a bit of integrity is required here.

No one alive, despite hubris to the contrary, knows for sure the answer in the scientific sense that we know the melting point of water from ice.

We all come to terms with this based upon culture, background, education, and intelligence.

This entire discussion MUST end up with no more substance than a discussion of favorite colours or favorite foods.

Personally I like Laotian food and the colour mauve.
