I still remember when I learned that the Sun was a star. I was six years old when my uncle told me about it. I actually asked him what the Sun was and his answer pretty much shocked me to the core. I already knew the Earth revolved around the Sun so learning that the Sun is just one of little tiny bright lights at night was a true eye opener. That night I looked up the sky again and wondered if there are other people up there.....
Oops misstype! We still have 5 billion years before we could refer to it as "was a star".....lol
I just type what comes to mind and rarely do editing.....
Actually, in narrative writing, as you were doing, you should use consistent tense. So you were correct to use "was," as the sun was a star back then, independent of the fact that it also is now.
That's probably why it just came naturally to me because I do read quite a bit and may have seen this word arrangement many times before. My subconscious mind were just spitting out words as I write them. English is only my second language though, I am so much better in Filipino.....lol
