P.S., how can the belief in no god be a fantasy? Check your logic, it doesn't make sense.
Refusing to believe in something for which there is and can never be objective proof is one thing. Going further and saying "because there is no objective evidence of the thing, the thing cannot exist" is a far different matter. The former is cautious and rational. The latter is a leap of illogic extending far beyond any proofs or disproofs, and is similar to those displayed by those who choose to assert the existence of a deity. Both are acts of faith unsupported by objective evidence.
If you are curious, I am a cautious, sceptical, and suspicious agnostic. I suspect a thing like unto what many call "God" based on personal experience, I am cautious about even thinking such experience constitutes objective evidence of that existence even to me - let alone others, and I am extremely skeptical of all stories others advance concerning the existence of their particular flavor of God and ABSOLUTELY SKEPTICAL of their claims to fully understand the will of such a being.
