<human>: Can you condense the text into three sentences or less?

I was instructed to present an informative speech over something both interesting for my audience (my fellow classmates) and be a topic I was already well informed about prior to the assignment. I know a lot about music, but I don't want to be the generic "kid" in the college class who just informs about bands no one cares about other than myself. I don't want to look like a tool and talk about guitar and piano ether. I like space, and history. I like conspiracies, sociological studies, movies, classic video games, and what not. I just can't decided what would be an ideal topic to actually present and I need to write this tonight. I'm desperate, please assist!!
