Still no answer as to why scientists make the claim that life originated from non-living matter without backing it up.
Not sure why you would say there is "still" no answer since this is the first time on this thread you've asked that.
Anyway, please provide an example of this being generally accepted by and claimed as fact by the community of scientists who study such things and it can be addressed. What can't be done is to accept your say-so that scientists (unnamed and no reference or citation their their words and published claims) they they are doing it.
So, when you provide this, we can deal with it.
Why can't respecting an individual's sincere belief be across the board? It should go both ways...Christian to Evolutionist...Evolutionist to Christian.
Why do you think it's admirable to respect a belief simply because it's "sincere"?
