I have not came across a single one. Even religious leaders and the Catholic Church admits there are no logical arguments for God. They were the ones to introduce logic and reason in their curriculum.
Maybe Catholics or church admits but not Islam. The concept of Trinity, in reality, is very illogical and absurd.
I think you misunderstand the very definition and types of logic and reason.
Give me the logical reasons for the denial of the existence of God and I will take it from there.
Intellect arrives at conclusions and theories which ultimately are subject to debate based on there weightage and soundness.
I have provided enough material regarding wisdom, ethics and reasons for God and the religion. Now it's your turn to put arguments.
By the way, I don't know if you went to Oxford or not but I went to Edinburgh and I am happy to engage in a constructive debate
The purpose of revelation is to provide the seal of truth on matters which cannot be solved through the consensus of the philosophers. Logic and reason without God’s revelation is just a never-ending debating exercise.
Purpose of life and ethics becomes self-made without the belief in God.
The analogy you gave of a unicorn is extremely wrong. The creator is demanding to ponder upon the intelligent design of the universe and his creations to conclude the existence of God. Unicorn’s presence at an unknown place doesn't make case for those signs.
How can you declare the default position to be disbelief?
What is your position on intuition & consciousness?
The sense of good & evil is ingrained in humans. Revelation only guides and support them to choose good & refrain from evil.
If someone follows black & white approach for good & evil than again he will be misguided, there are a lot of matters in which apparent wrong acts are not only allowed but become a compulsion on a person to act upon.
In short, Wisdom is something which demands more than simple B & W approach.
