[Right Wing Professor]

We don't teach alternatives to gravity because without its existence none of us debating this issue, or any other, would be here to do so.

And this is different from evolution how?

...and this is different from evolution how...

Not to answer a query with a query, but are you stipulating that without evolution, as without gravity, we would be equally bereft of the chance to exist? A remarkable leap, I think, almost, one could say, a leap of faith...again, I ask you, how do you equate evolution and gravity as unassailable concepts?
