No offense, but this is crap. If the "beneficial symbiotic relationship" included the strains that cause Malaria, then it isn't beneficial. And if it
didn't include those parasitic strains that cause Malaria, then those parasites WOULDN'T HAVE A LIFECYCLE - and therefore wouldn't survive or propagate, and their "creation" would have been for nothing.
Remember, as
@Jose Fly pointed out already, under creationism one has to claim that these parasites were created mostly "as is" - you don't get to say they turned "evil" or something "after the fall" and therefore were imbued with more genetic information. Unless you want to admit that God did that, and made these parasites deadly in order to kill humans.
Besides... at the time "before the fall"... guess how many humans there were. Oh that's right... you know. There were TWO. What the heck kind of "symbiotic relationship" could there be between 2 unique beings and a bunch of mosquitoes? Better hope those bites are pretty damn "beneficial".
You sit there and hint and imply that people are wasting their time... that "it's fine if you want to do that, but...", and here you are, posting things like this? Pot's black... kettle's black... give it a rest.
