" ... many believe that everything came about by itself ,without any observable evidence ..."

And pete and his fundamentalist mates believe that God did it ... without any observable evidence ... ?

Oh yes, pete, through some sort of oversight, you don't seem to have provided any answers to those questions I posed recently. Just to refresh your memory, here they are again:

1. If 'it' was all made by a Maker, who made the Maker?
2. Who made the Maker's Maker - and so on in an infinite regress?
3. Where did the Maker get his materials from?
4. Did the Maker create his materials from 'nothing', by any chance?
5. What materials is the Maker made from?

Do you need more time or are you working feverishly on them as we speak?

Finally, have you read Prof. Dawkins' book yet?
