Consider the malaria protozoa (left). Flying creatures, birds and mosquitoes, were created on day five. Everything else, including man, was slapped together in a hurry on day six. Between crafting elk and mole rats He constructed a small tube of protoplasm specifically designed to murder millions of humans, mostly children, every year.
Malaria is a human parasite. It doesn't bother with cows or chickens, it will only use human blood cells to reproduce. The mosquito is merely the trolley it uses to travel from victim to victim. For pure heartless butchery, malaria is master of the world. No human despot, not Hitler nor Stalin nor Mao, can match the human suffering of this creation of God. One to three million dead, half a billion sick, every year.
