There's nothing new here. People have been slandering God ever since Eden. (Why, oh why do you surf by this junk, Sis?
) This guy's particular allegations are rewarmed so often they must have botulism by now! I mean, how many times does the Church have to deal with the same lies?
His "nearly identical" title reminds me of one of my Sisters, who is adopted. We bear absolutely NO physical resemblance to one another (among other things, wer are of different ethnicities). Yet, when I introduced her to people when we were growing up, people would always say, "Oh, yes, I can see how much you look alike" and my Mom would say, "What, they both have two eyes, a nose and a mouth?"
At this point, the only thing I really tell DD is that there ARE fake gods out there -and that they appear a lot in history. And, that their stories have a big impact on modern culture (for instance, several planets were named for them).
She doesn't need to know every lie people have told about God until she asks - or until we do an apologetics course when she is much older.
