Sin coming into the world w/Adam and Eve began the possibility/probability for natural disasters.
False.
Our planet is a few BILLION years old. Adam and Eve are fictitious people from an allegorical story, as most churches teach nowadays. Let us suppose, for an instant, that they actually existed, and were homo sapiens like us. To be charitable, let's say they lived 10,000 years ago.
So what you are saying is that for the entire, 4 billion or so year history of our planet, there was never a "natural disaster" until the last 10,000 years or so, an instant in the lifetime of our planet.
You are saying that the earth's crust was not moving (so there were no earthquakes), it was sealed to all magma (so there were no volcanic eruptions), the climate was mild all over the planet (there were no ice ages, no large storms, no tornadoes, no tsunamis, no heat waves, ...), there were no floods, etc etc etc
Then all of a sudden, in the last instant of the earth's existence, two people ate from a tree, so the earth instantaneously developed plate tectonics, weather phenomena, and all that. Yeah it makes perfect sense doesn't it!
Besides, who determines what a "natural disaster" is? If any one event in the earth's history can be called a disaster, it is the collision of an asteroid with the earth about 65 million years ago that led to the extinction of the dinosaurs. Now that was definitely a "natural disaster" for the dinosaurs, but it was a tremendous blessing for our mammal ancestors, who were no longer appetizers for T-rex.
Our friend Colossus_500 says that until the fall of Adam and Eve, lions and other such carnivores didn't eat humans. Homo sapiens have been around for about 150,000 years. Other similar species (homo habilis, homo ergaster, etc) have been around for 4 million or so. Presumably, lions didn't eat any of them for all that time, but when that naughty woman ate from a tree, the cats suddenly developed a taste for human flesh. Yeah, makes perfect sense.
When will people learn that:
1. Sin does not cause earthquakes, plate tectonics does.
2. Sin does not cause plagues, germs do.
3. Sin does not cause floods, intense rainfall does.
