When you ask for proof, I ask you - do you know who your great, great grand father was and if indeed there is proof of his existence? How do YOU prove it? When you say that you had a great, great grandfather, then that is "faith". There is NO PROOF that he ever existed, is there?
Why don't you answer that question directly and then we can discuss further.
( I know tha you will start some ranting and raving about Lorsd Rama, USA Germany and Christian schools et., but tyr to answer honestly once.
