"Otsutsuki's are aliens with no relationship to humans. Only hagomoro was a cross of alien and human. You cannot compare otsutsuki physiology and abilities to that of humans. They have rinnegan on their hands and only urashiki has a rinnegan in his left eye. At least for hagomoro and his transmigrants, for them to achieve the rinnegan ,they need to have a base sharingan. For an uchiha to awaken the rinnegan he needs to have indra's chakra and a sharingan. There has been no person on Naruto earth who awakened a rinnegan without a sharingan."

This was a riot to read. Why can't I compare how an Otsutsuki awakens Rinnegan and a human? What evidence does anyone have that the awakening of Rinnegan is different due to Otsutsuki genes? Nothing.

That very last sentence too. There hasn't been a single Eight Gates user without bushy eyebrows, but that ain't a requirement. Momoshiki doesn't have Sharingan. Therefore it's not a requirement, for anyone until proven otherwise.
