I'm asking if you think that it's OK that it isn't literally accurate, but simply provides narrative.
It was understood then and it is understood now that the Creation painting uses symbolism to illustrate concepts that cannot be shown literally, God with a long white beard, (a father of mature wisdom, worthy of respect), vs. Adam beardless (inexperienced, child-like innocence).
Using this painting to show how clean a shave Adam had in a razor blade commercial, say, would be quite the contrary.
Really and truly, You do grasp how symbolism is used, yes?
