Well, you've just wasted 5 minutes of my life. What was the point of that video? Okay, you love aliens and space… so? Look at it from a viewer's perspective. Would you, as someone who's interested in this subject, be interested in listening to a person rambling on about herself and things everybody already knows? You say you've been obsessed with aliens for a long time, yet you can't think of something to talk about?
You could post reviews of UFO books/movies, talk about the various theories on the true nature of aliens, the controversies surrounding the ancient aliens theory, you could interview UFO researchers, discuss some of the conspiracies that most people haven't heard of, or debate sceptics. The sky's the limit.
One thing you should definitely do, is write a script and memorise it. It'll save you from doing more incoherent videos. If you want to build a good channel, you have to be prepared to put some work into it. That's the difference between a true Youtuber and some girl with a camera. Good luck.
