First he creates a world where evil is possible. Why did he do that? If he had not done that, there would have been no need to send prophets/sons/messengers/manifestations/mahdis. If a God exists, then there is no justification whatsoever for his creating the universe or letting evil and disasters torment the world.
..so you know better than G-d.
Whatever you say, reality will not change.
Your alternative "theory" is that G-d doesn't exist.
To me, that is irrational. I don't believe that this world has no reason for its existence.
The so-called "problem of evil" is all about mankind's suffering, and so a Loving G-d cannot exist. This is false.
A Loving G-d allows souls to grow in righteousness that enables them to live forever in paradise. This life is of limited suffering, although very real. The suffering in the next life could be even worse, and could be for a very long time.
Male and female .. hot and cold .. yin and yang .. these are concepts that we all understand. It is part of reality.
That can't change, whatever one believes.
The only thing that changes is what is in store for us. That can be changed by pursuing righteousness. G-d wants us to learn.
Some oppose mankind in order to stunt their learning.
They cannot permanently damage believers. It is only temporary.
The love of G-d is the most important thing in a person's life.
"
Love the Lord your
God with all your heart, with all your soul, with all your strength, and with all your mind, and
love your neighbor as yourself".
That is the foundation of faith. It is that which brings mankind success, as those who do it will be obedient and vigilant and want to learn more. They will be motivated in a way that overrides their base desires, which rises them up to a civilisation which excels all others. Amen.
