Those who oppose evolution might achieve some credibility in these threads by making an effort to understand what they're arguing against.
The Theory of Evolution. (Excellent introductory encyclopedia article.)

It would also be useful to learn what science is: The scientific method.
And you need to know this: What's a Scientific Theory?

15 Answers to Creationist Nonsense. From Scientific American

This thread looks pretty hopeless so far to me, but good luck!

Great links. I just skimmed the 15 answers. Creation "science" is an oxymoron, isn't it? The funniest part of "intelligent design" for me is its inherent paradox, not mentioned in the 15 answers: if design is required for any phenomena of sufficient complexity, then who designed God?

15 ways to refute materialistic bigotry: A point by point response to Scientific American

[TeaDumper]

The article in Scientific American was pathetic. Rather than straight up refutation it merely offered theoretial extensions on theoretical extensions Not quite what I would call scientific.

A better theory on origins and one that stands up to more scrutiny is the theory that aliens planted life here. I didn't say I believed it, it just stands up better to criticism.

If that is the best that Scientific American can do then they better consider deleting Scientific from their name.
