Hagoromo Question

[GDnaruto]

I don't want to go back and read it so i want to ask you guys.
Was it ever mentioned why he inherited the rinnegan?

 

[Flakez]

Because Kaguya ate the fruit.

 

[Rohan]

Because Kaguya ate the fruit.

Still, it's weird that Hamura never obtained the Rinnegan. And the Third Eye.
