God and Natural Evil
The greatest threat to my Christian faith is the existence and abundance of Natural evils which have existed since the beginning of time eons before humanity and eons before Adam and Eve. A suffocating, unbreathable atmosphere in the early earth during the Precambrian era, intense cold, intense heat, violence, predation, killing, venomous creatures such as jellyfish, stonefish, spiders, scorpions, centipedes, parasites such as screw worm flies, mosquitoes, ticks, fleas, lice, excrement, mold, mildew, hurricanes, tsunamis, tornadoes, birth defects, miscarriages, and worst of all, the legion of diseases which torture and kill man and beast. Suffering, death, and extinctions since prehistoric times. And frightening monsters such as sharks, crocodiles, Dinosaurs, lake serpents, and sea serpents. A loving merciful creator God would not have created such horrible things. It just doesn't make sense to me.
