jon preston - " to say atheists and agnostics and others are wrong is downright....strange". - many things in the science field are still 'theory' they can be wrong, they can't be proven.
Years from now some of what is being taught or understood may be equivalent to several hundred years ago when most believed the Earth was flat.
I'll demonstrate how it doesn't have to be just one or the other for possibilities.....let's say God and all life began from random chance and grew after somehow single cells developed are both wrong.....
Some possibilities...... 1. We are in the middle of the chain of life and find out all of life on Earth was due to another intelligent life form, far advanced beyond us, learned how to create biological life. We are the result of what began as biological robots. It won't answer where they come from, but it's a step in learning what happened.
2. God, whatever and whoever he is, could even be part of the above example, created all, but as the bible says and hints although most people have failed to see it, says that Earth and man were divided among the sons of God to rule them and YHWH inherited Israel. That would answer those who wonder why he would be jealous, or seemingly different attributes from who Jesus says are part of the Father, if they were two different entities.
3. There was another world before that was mostly destroyed, this one came from the remnants of that, or those that fled it, or this world itself. Again it won't explain the origin but would still be a step closer.
