The Poem Book That Shouldn't Be Seen [P1: If It Goes Up, Must Come Down]

Seven civilizations superior to ours of a million stars.

A sphere capable of containing a sun inside it to collect energy,
If that is found there would be life much more superior to ours,
They told us about this in biology,
It was thought that they had already been located, some hours ago.

Seven out of a million,
Will there be any star like you among those seven civilizations superior to ours of a million stars?,
It's even more likely that they are eleven times your size, I enter into reflection,
Ten times in my fears.

I keep thinking about you,
I keep dreaming about you,
I keep crying before sleep for you,
But I still talk to anyone but you.

So who are you?
