Can a 25 year old date a 40 year old man?

I completed an internship somewhere and a guy who used to work there added me on LinkedIn. Then he messaged me to ask how I was and I didn’t even remember who it was at first. Then he said we worked in the same office and explained his position. He also said we made eye contact once. He said he never had the pleasure of meeting me. Then we started talking about work etc. from what I remember he was a decent looking guy, but he was definitely not my age. I actually looked up his CV and if I’m not mistaken he’s in his late 30s or around 40. Is that creepy?
