Something like that, yeah.
Or, to take it a step further, he could have made the Bible less ambiguous. He could have come out and said that slavery is evil, don't do it. Instead he sets down rules and guidelines about how to properly beat your slave and how slaves should be good to their masters. He could have said that you don't need to sacrifice animals to worship me, all you need to do is pray and I'll hear it. Instead he commands sacrifices and savors the smells. Instead of saying that gender equality is awesome, he told women to shut up in church. Instead of ordering his people to murder countless men, women, and children he could have easily came down from heaven and told the enemy cities worship me. But he didn't.
It is for those, and many more, reasons that I believe the Bible to be just a book and God to be a creation of evil men to justify their wicked ways.
