Right well now Nika is very confused. "I though astronomy was about stars and planets not aliens." She muttered silently so no one could hear her. So are there aliens or not? If there isn't a definite answer then why are they trying to learn about them!? AHH!!! This is all just too much for her little brain to handle. "I think Aliens might exist. Maybe not in our galaxy, but maybe in others. We've already said that they don't have to look like us at all." She said then she came up with a weird sort of question. "Professor, isn't the Earth pretty new compared to other places? What if there is this really old planet out there in another galaxy far away right... And our technology has been advancing at a really fast pace. So what if there technology is even more advanced because they're older than our planet. Then could that mean they're watching us right now?" Her thoughts were starting to get all jumbled up now.
