Sanhedrin 38: What Is Man That Thou Art Mindful of Him?

On a busy daf, the discussion turns to the creation of humanity -- beginning with the creation of one man (and only one as the starting point), and each person's individuality. The question of why humanity begins with only one person occupies the Gemara for a while - including the potential arguing or pride or faulting that could happen if there were more than one ancestor of origin. Also, a description of the creation of man, where God seems to consult with the ministering angels (which He also creates), and how that creation-by-committee doesn't take place at all (God destroys the angels who question His plan!). But then humanity turns, as expected, destructive and the angels basically note to God that they told Him so. God answers them (via a biblical verse) that He is nonetheless going to care for His creations (humanity).
