"Since you claim the intellectual high ground here, asking me who made God is merely evasion."

No it's not - it's an obvious question!   

"I don't believe in a God who needs creating himself."

Surely, it's not just a question of 'belief', is it, Pete? You can't call on (your very peculiar versions of) 'logic and 'reason' when it suits you and then ditch them for 'belief' when it doesn't.   

"To demand who made him is thus just the same as saying , you don't accept there is a God, since at least in Christian teaching, the eternal, and God, are synonymous."

If this 'debate' is really about logic, reason and science (oh, if only it were!) then no questions are impermissible; appealing to pious religious waffle convinces no-one.

"It is an observable scientific principle that life only comes from life."

"Christians believe that he is living and though it is not a giving of life in temporal terms, he has given life to his creatures."

Declaring that God created life (out of nothing) because Christians believe He did is all about faith - and faith has nothing to do with 'logic' and 'reason'.

The trouble with you, Pete, is that you don't actually know what 'logic' and 'reason' are, do you? You constantly confuse these terms with 'belief'. Time after time you tell us that a particular scientific discovery is not 'logical' or 'reasonable' merely because you have chosen not to believe it. My advice to you is to stick to religion and leave the science to the scientists!
