They say that Celestials never interact with humans as they are divine beings from mythology but if they did interact with humans they will be forced to coexist with humans let alone their powers but that’s why one Celestial is 4000 years old but looks like a person in their 20’s China aka Yao Wang or Wang Yao is a Celestial and he is the oldest and never interacted with anyone on earth but his siblings are Celestials in the Celestial Realm but it will be his first to arrive on Earth.
