There is an episode of Doctor Who where the Doctor, an alien that looks like a young man, is talking to Wilfred, an old human man.
Wilfred: Oh! 1948. I was over there. End of the Mandate in Palestine. Private Mott. Skinny little idiot I was. Stood on this rooftop in the middle of the skirmish. Like a blizzard, all them bullets in the air. The world gone mad. Yeah, you don’t want to listen to an old man’s tales, do you.
The Doctor: I’m older than you.
Wilfred: Get away.
The Doctor: I’m nine hundred and six.
Wilfred: Oh really though?
The Doctor: Yeah.
Wilfred: Nine hundred years. We must look like insects to you.
The Doctor: I think you look like giants.
