What era do you want to live to?

At first, I could not understand exactly what the question is. I thought Iit’s the age that we answer when we were are asked “how old are you?”. But I knew, that It was my misunderstanding. I misunderstood it.
I understood the exact meaning of “era” so I can answer now.

I want to live in the prehistoric times and the middle age. The reason why I want to live in the prehistoric times is the mysteries of nature. At that time, Tthere were dinosaurs, mammoth and so on. If we saw them directly, they'll they'd be very dangerous but we can only see them by through pictures or fossils now. I will feel It could be an exciting experience that which I've never been had.

Next, I want to live in the middle age. I feel the middle age is noble and elegant. If I have lived in the middle age, I’d like to learn how to build the buildings. There were styles of architecture like the Gothic and the Baroque form.
I’ll build a beautiful Catholic church that there is could have only one in this world.
