I really have no problem with embedded age as a concept (that is not to say I think that is what God did) but embedded history is inherently deceptive.
If God created Adam as a full-grown adult because that is what was necessary for him to survive, then that is embedded age and theologically (IMO anyway) fine. If, however, God created Adam with a scar on his knee such as would be sustained in a fall, that is embedded history and, since the fall that would have caused the scar never actually happened, God gave Adam a history that didn't exist. That IS deceptive.
What we see everywhere in the universe is the same. If the universe and our world are indeed only 6,000 years old, then God has given views of things that never happened. That is deceptive no matter how you try spin it.
