So why doesn't God just set 99.9% of all biologists straight, to eliminate confusion among people?

its not a perfect world. belief in God means belief in the darker side as well, and with that comes all the confusion and malicious crap from people who have nothing better to do than spread their athiesm around and persecute the believers. God in any of his books didnt tell us that life here would be easy, rather that this life is a test to see where we will end up in the hereafter...which is much much longer than our short lives on this earth. may He guide us all to the straight path.
