""does not " the preservation of favoured races " not presuppose the "weeding out" of those not so favoured ?.""

No, it doesn't! Evolution has no goal, target or preference.

What you describe as "weeding out" is nothing more than the inability to adapt sufficiently for survival. There is nothing as purposeful as "weeding out" in that.

And even if all you say about evolution theory were true in every detail, that still isn't evidential proof of the existence of God, the inerrant nature of the bible, or even the need for either to exist.

Instead of belittling and sneering at the achievements of men far exceeding your abilities in any field, why not present YOUR testable and falsifiable evidence for YOUR claims?
