When I see a tsunami killing 280000 muslims, men women and kids, in Sumatra, I can't believe that a great misericordious god can exist, and that God or Allah believers are very logic.That is why I say that Atheists are the most unreasonable and most illogical persons on the face of earth.
If they were actually blinds, at least there was some excuse for them, but having eyes and seeing the world around us and still believing that they come out by themselves, means that he does not have eyes.
Same when in Italy, after a first seism part of the population took refuge in the village church, second seism destroyed only the church killing all who sheltered into it.
Believers are sure very logical.
While I was a woodwork designer, each time I was ordered to draw a baby coffin, I wondered who's that god believers do pray at.
