Why would Hagoromo have a Sharingan when he gets genetically he has the step above it. He was never described as having it and the Rinnegan was always described as "his eyes"

No one with just a Sharingan/MS ever said "I HAVE HIS EYES I AM THE NEXT SAGE OF SIX PATHS"

Sharingan happened because the Rinnegan didn't have Senju. Born with Senju and Uchiha in him he wouldn't have that problem. If he started with a Sharingan and ended with a Rinnegan then there isn't a reason an Uchiha shouldn't be able to do it like with Sharingan to MS
