I don't think DNA proves ancestry.
And yet it always confirms evolutionary predictions.
Mmm ... looks like proof to me.
Man can be created independently of chimps, using much of the same base materials. You can't determine where something came from just by looking at the end product, you have to trace it to its source. That's like buying two meat products at the grocery store and concluding that they came from the same farm because they have the same manufacturer label on it.
No it isn't. It's like doing a DNA test to determine relatedness, a procedure which we know to work.
