So, with god, all things are possible to which a sound atheist would say 'that's for sure!'.
One other thought; man of, say, 5,000 or 50,000 or 150,000 years ago, if he could write to us in a way we understood, he wouldn't be speaking of an Abrahamic god. He couldn't do so any more than the Chinese would or could if they'd made this stuff up. They'd pass on the myths and superstitions they came up with to explain the unexplainable. Another way to put that is if a child born today could be isolated from ALL religious material yet free to learn biology, astronomy, geology and physics, would they come up with anything resembling an Abrahamic or Buddha based faith? Let's turn that around; if we could send our knowledge back to man of 5,000 or 50,000 or 150,000 years ago in his way of understanding, what's more likely, that he'd reject it as heresy, lies, deception or would he sit back and say "Huh, well, that makes a whole lot more sense. Honey, stop the sacrifice. That's not how it works it seems..."
