god created a paradise, there was no earthquakes in Eden. Eve decided to listen to a snake rather than obey the holy spirit and so had to leave paradise for an imperfect world that had earthquakes.
Suffering is a necessary test for everyone to prove their faith, didnt you see my previous post, "when you die it will all have been worth it. He has a plan just wait and see, he will prove it to you in heaven."
Knowledge is a double edged sword, it takes you further from god's word. Just look at what is happening in the world.
When you study the true god and put your faith in him he will show himself to you. Obviously those who just dismiss him don't know what its really all about because they don't believe.
