I can understand your anger over the human condition.
Oh, I've got no anger. I lead a very satisfying, prosperous life. I just don't understand why a omni-everything creator, who pretends to be good, would turn so many children blind. Obviously, you can't either. It angers me when you try to tell me that a "good god" made those worms and that I have to worship that monster.
I would certainly call the human eye a masterpiece..
Me too. The human eye certainly is a masterpiece. Scientifically, the human eye can be explained.
However, my eyes are not masterpieces when I do scuba diving. Those squids see way better than me in those conditions! I see better on land that they do. They see better in the water than I do.
As to why humans suffer, the Bible explains that this was not God's purpose for mankind, and he has been taking steps over many centuries to end such suffering for all future time. (Romans 8:20,21)..
If a god "wanted" or has or had a "purpose" for anything, he or she could do it with waving a little magic wand. He or she could just wave those parasites, blinding children, away. Your "explanation" makes no sense at all.
Much of the suffering today is man-made, either through ignorance, greed, malice or a combination thereof.
Are you trying to tell me that those parasites turning children blind were man-made? They're not. they are in the water.
Did you read your Bible? It says that your "good god" made everything.
Are you telling untruths by denying that your god made those parasites? Because, according to your religion, that same god made everyting. Even the devil. Everything. I'll repeat, everything. What did those children do wrong to deserve those worms getting into their eyes?
