I don't believe in God.
I don't really know why, I just can't imagine putting faith into someone who I've never seen, heard; someone who stays incognito, should we say. I mean, if you believe in God, you might as well believe in Phantom, seeing as they're both supposedly 'silent helpers of the needy'.
I come from a Hindu family and as some may know, Hindus have several Gods and Goddesses. This caused a split between the Hindus and there used to be major wars between Vaishnavites (followers of the God Vishnu) and Shaivites (followers of the God Shiva). In ancient scriptures, some of the teachings of these Gods are 'You mustn't fight each other' and other similar things, but then we've got Gods who go around holding weapons and killing each other, I mean WTF? =\
The three main Gods in Hinduism are Brahma (the Creator), Vishnu (the Protector), and Shiva (the Destroyer). These are just based on the circle of life - Creation -- When your born, Protection -- The time you live for, Destruction -- Death. People in the olden days would've given these stages in the circle of life a form -an image and a name- so it was easier for them to understand how things worked.
I don't find faults in those who do believe in God, but to me it's just a word used for people who've supposedly done extraordinary things.
