I wonder how he even can be an Ootsutsuki... I mean, there are no Senju to be seen these days and yet there were still many around not more than 50 years back, so one would expect Kaguya's original bloodline to be extinct (unless Kaguya married to Ootsutsukis) but still, if Ootsutsukis were a thing in the present, one would hear of them or not? So the only explanations I can think of:
 * he is immortal like Kaguya
 * time-travel
 * stasis through means of fuuinjutsu of having been frozen
